Requirement for Proof of Negative COVID-19 Test or Recovery from COVID-19 for All Air Passengers Arriving in the United States
If you plan to travel internationally, you will need to get a viral test no more than 3 days before you travel by air into the United States (US) and show your negative result to the airline before you board your flight, or be prepared to show documentation of recovery (proof of a recent positive viral test and a letter from your healthcare provider or a public health official stating that you were cleared to travel).
On January 12, 2021, CDC announced an Order requiring all air passengers arriving to the US from a foreign country to get tested no more than 3 days before their flight departs and to present the negative result or documentation of having recovered from COVID-19 to the airline before boarding the flight. Air passengers will also be required to confirm that the information they present is true in the form of an attestation. This Order is effective as of 12:01am EST (5:01am GMT) on January 26, 2021.
For the full list of requirements and exemptions, please review the language in the Order.
International Travel Recommendations
International travel poses additional risks and even fully vaccinated travelers are at increased risk for getting and possibly spreading new COVID-19 variants.
CDC recommends delaying international travel until you are fully vaccinated.
Follow CDC’s after international travel recommendations.
Frequently Asked Questions
This Order applies to all air passengers, 2 years of age or older, traveling into the US, including US citizens and legal permanent residents.
The CDC order does not replace the Presidential proclamations. Therefore, a negative test result for COVID-19 or documentation of having recovered from COVID-19 to the airline before boarding the flight does not exempt a foreign national from the travel restrictions outlined in the Presidential proclamations.
With specific exceptions, several Presidential proclamations suspend and limit entry into the United States, as immigrants or nonimmigrants, all noncitizens who were physically present within specific countries during the 14-day period preceding their entry or attempted entry into the United States.
For a full list of countries and links to the proclamations on the White House website, visit Travelers Prohibited from Entry to the United States.
No, the Order to present a documentation of a negative COVID-19 test or recovery from COVID-19 does not apply to air passengers flying from a US territory to a US state.
US territories include American Samoa, Guam, the Northern Mariana Islands, the Commonwealth of Puerto Rico, and the US Virgin Islands.
If you booked an itinerary from a US state or territory to another US state or territory and the itinerary has you taking a connecting flight through a foreign country, you do not need to be tested. An example of this situation is an itinerary booked between the Northern Mariana Islands (a US territory) and the US mainland via Japan.
For information about what to do if you have a short trip to a foreign country from the US, see FAQ Can a test taken before departure from the US be used to return within the 3-day timeframe? How will testing requirements be handled for short trips?
The 3-day period is the 3 days before the flight’s departure. The Order uses a 3-day timeframe instead of 72 hours to provide more flexibility to the traveler. By using a 3-day window, test validity does not depend on the time of the flight or the time of day that the test was administered.
For example, if a passenger’s flight is at 1pm on a Friday, the passenger could board with a negative test that was taken any time on the prior Tuesday or after.
An attestation is a statement, writing, entry, or other representation under 18 U.S.C. § 1001 that confirms that the information provided is true.
No, the requirements of this Order only apply to air travel into the US.
The airline will confirm a COVID-19 negative test result or documentation of recovery for all passengers before boarding.
Passengers must be tested with a viral test that could be either an antigen test or a nucleic acid amplification test (NAAT). Examples of available NAATs for SARS-CoV-2 include but are not restricted to reverse transcription polymerase chain reaction (RT-PCR), reverse transcription loop-mediated isothermal amplification (RT-LAMP), transcription-mediated amplification (TMA), nicking enzyme amplification reaction (NEAR), and helicase-dependent amplification (HDA). The test used must be authorized for use by the relevant national authority for the detection of SARS-CoV-2 in the country where the test is administered. A viral test conducted for U.S. Department of Defense (DOD) personnel, including DOD contractors, dependents, and other U.S. government employees, and tested by a DOD laboratory located in a foreign country also meets the requirements of the Order.
Rapid tests are acceptable as long as they are a viral test acceptable under the Order.
International air passengers traveling to the United States can use a self-test (sometimes referred to as home test) that meets the following criteria:
- The test must be a SARS-CoV-2 viral test (nucleic acid amplification test [NAAT] or antigen test) with Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration (FDA).
- The testing procedure must include a telehealth service affiliated with the manufacturer of the test that provides real-time supervision remotely through an audio and video connection. Some FDA-authorized self-tests that include a telehealth service may require a prescription.
- The telehealth provider must confirm the person’s identity, observe the specimen collection and testing procedures, confirm the test result, and issue a report that meets the requirements of CDC’s Order (see “What information must be included in the test result?” below).
- Airlines and other aircraft operators must be able to review and confirm the person’s identity and the test result details. The passenger must also be able to present the documentation of test results to U.S. officials at the port of entry and local/state health departments, if requested.
For travelers who test positive, CDC recommends the telehealth provider report positive test results to relevant public health authorities in the traveler’s location following local requirements. The telehealth provider should also counsel the traveler on what they and their close contacts should do. This would include not traveling until they complete isolation (if infected) or quarantine (if exposed), in accordance with local requirements.
Some countries may restrict importation of tests that are not authorized or registered there. Travelers who are considering bringing a U.S.-authorized test with them for use outside of the United States should contact authorities at their destination for information before they travel.
A test result must be in the form of written documentation (paper or electronic copy). The documentation must include:
- Type of test (indicating it is a NAAT or antigen test)
- Entity issuing the result (e.g. laboratory, healthcare entity, or telehealth service)
- Specimen collection date. A negative test result must show the specimen was collected within the 3 days before the flight. A positive test result for documentation of recovery from COVID-19 must show the specimen was collected within the 3 months before the flight.
- Information that identifies the person (full name plus at least one other identifier such as date of birth or passport number)
- Test Result
Airlines and other aircraft operators must be able to confirm the test result and review other required information, and should determine when translation is necessary for these purposes. Passengers whose documents are in a language other than English should check with their airline or aircraft operator before travel.
Individuals who are not fully vaccinated and have had close contact with a person with COVID-19 (i.e., who are considered exposed to COVID-19), should self-quarantine and NOT travel until they have met CDC criteria for discontinuing quarantine. Individuals who are fully vaccinated, or who have documentation of recovery from COVID-19 in the past 3 months, do not have to self-quarantine after exposure to a person with COVID-19 and can travel unless they have COVID-19 symptoms.
Diplomats and special visa holders are not exempt from this Order.
Yes, at this time all air passengers traveling to the US, regardless of vaccination or antibody status, are required to provide a negative COVID-19 test result or documentation of recovery.
Get tested no more than 3 days before your flight to the US departs. Make sure to be tested with a viral test (NAAT or antigen test) to determine if you are currently infected with COVID-19. Also make sure that you receive your results before your flight departs and have documentation of your results to show the airline.
Federal testing requirements must be met to board a plane to the US. Some state and local governments may have similar or more restrictive testing requirements for air passengers arriving in their jurisdictions. Always check and follow state and local recommendations or requirements related to travel in addition to federal requirements.
If a trip is shorter than 3 days, a viral test taken in the United States can be used to fulfill the requirements of the Order as long as the specimen was taken no more than three days before the return flight to the US departs. If the return travel is delayed longer than 3 days after the test, the passenger will need to be retested before the return flight.
Travelers considering this option should additionally consider the availability of appropriate testing capacity at their destinations, and the time frame needed to obtain results, as a contingency when making plans for travel.
CDC does not recommend getting tested again in the three months after a positive viral test, as long as you do not have symptoms of COVID-19. If you have had a positive viral test in the past 3 months, and you have met the criteria to end isolation, you may travel instead with documentation of your positive viral test results and a letter from your healthcare provider or a public health official that states you have been cleared for travel. The positive test result and letter together are referred to as “documentation of recovery.”
A letter from your healthcare provider or a public health official that clears you to end isolation, e.g., to return to work or school, can be used to show you are cleared to travel, even if travel isn’t specifically mentioned in the letter.
Air passengers traveling to the US are required to present a negative COVID-19 test result or documentation of recovery. Airlines must confirm the negative test result or documentation of recovery for all passengers before boarding. If a passenger chooses not to present a test result or documentation of recovery, the airline must deny boarding to the passenger.
Passengers should contact the airline regarding options for changing their departure date to allow time for a test, see if the airline has identified options for testing, or if there are options available for changing their flights to transit through a location where they can get tested before boarding their final flight to the United States.
Travelers should consider the availability of appropriate testing capacity at their destinations, and the time frame needed to obtain results, as a contingency when making plans for travel.
For more information on where to obtain a test overseas, travelers should review the relevant U.S. Embassy websiteexternal icon. Travelers may need to consider a routing change to a different country or city in order to meet the testing requirement.
People should self-isolate and delay their travel if symptoms develop or a pre-departure test result is positive until they have recovered from COVID-19. Airlines must refuse to board anyone who does not present a negative test result for COVID-19 or documentation of recovery.
Before boarding a flight to the US, you will need to show a paper or electronic copy of your negative test result for review by the airline and for review upon request by public health officials after you arrive in the US.
If you are traveling with documentation of recovery, you must present paper or electronic copies of your positive test result (dated no more than 90 days ago) and a signed letter, on official letterhead that contains the name, address, and phone number of a licensed healthcare provider or public health official, stating that you have been cleared to end isolation and therefore can travel. A letter that states that you have been cleared to end isolation to return to work or school is also acceptable. The letter does not have to specifically mention travel.
Airlines and other aircraft operators must be able to confirm the test result and review other required information. There should be sufficient personally identifiable information on the test result or documentation of recovery to ensure a match with the person’s passport or other travel information. This could include but is not limited to name, date or birth, age, passport number, etc.
Airlines and other aircraft operators should determine when translation of results or documentation of recovery is necessary for these purposes. Passengers whose documents are in a language other than English should check with their airline or aircraft operator before travel.

Exemptions may be granted on an extremely limited basis when emergency travel (like an emergency medical evacuation) must occur to preserve someone’s life, health against a serious danger, or physical safety and testing cannot be completed before travel.
CDC may grant a humanitarian exemption in limited circumstances only when an individual must travel to the United States to preserve health and safety (e.g. emergency medical evacuations) and is unable to access or complete the testing requirement before travel. Individuals and organizations sponsoring individuals who fit the exemption criteria described in CDC’s Order should contact the U.S. embassy or consulate in the country from which they are departing for the United States. The embassy will then transmit this information to the CDC for consideration.
You can contact the nearest U.S. embassy or consulateexternal icon, or call these numbers at the U.S. Department of State headquarters: From the United States and Canada: 888-407-4747; from overseas: 202-501-4444
NOTE: A humanitarian exemption is not needed for people who need to travel via private or medical transport to the United States after testing positive for COVID-19. People who test positive for COVID-19 and have not met CDC criteria to end isolation are exempt from the requirements under the Order if they travel via private or medical transport to the United States. The aircraft operator transporting the person must adhere to CDC’s Interim Guidance for Transporting or Arranging Transportation by Air into, from, or within the United States of People with COVID-19 or COVID-19 Exposure. CDC’s guidance states that other passengers who do not have COVID-19 should not be transported with infected passengers. If a parent or caregiver is required to accompany a minor or other infected person needing assistance during travel, that person must apply for a humanitarian exemption if unable to be tested within 3 days of the medivac departure.
To facilitate the review of a humanitarian exemption request, the following information should be provided to the embassy or consulate for transmission to the CDC:
- For each passenger: Name (family name/surname, given name), Passport number and Nationality
- Cell phone, including country code, of passenger or head of household if family unit
- Email of passenger or head of household if family unit
- U.S. destination address
- Is U.S. destination home address?
- Departure date and flight itinerary, including any connecting flights
- Name of submitting entity if different from passenger
- Name of company submitting on behalf of passenger(s) (if applicable)
- Name of point of contact (POC) submitting on behalf of passenger(s) (if applicable)
- Phone and email address for POC submitting exemption request on behalf of passenger(s) (if applicable)
- Purpose of travel to the United States (provide brief explanation of why urgent travel is needed, and how travel will contribute to health and safety of passengers(s))
- Justification for testing exemption (e.g. no testing available, impact on health and safety)
- Documentation to support justification for test exemption (e.g. medical records or orders for medical evacuation)
See the Department of State’s websiteexternal icon for more information on assistance for U.S. citizens overseas.
Passengers are only required to retain a paper or electronic copy of their negative test result or documentation of recovery for the entirety of their itinerary. The attestation should be submitted to and retained by the airline or aircraft operator.
Yes, passengers must still retain a paper or electronic copy of the necessary documentation as federal public health officials may request to see these documents at the port of entry. State, territorial, tribal and/or local health departments in the United States may also request them under their own public health authorities.
Yes. Any flight entering the US, even for a connection, will require testing before departure.
If your itinerary has you arriving to the US via one or more connecting flights, your test can be taken within the 3 days before the departure of the first flight.
If the 3-day testing period expires before one of your connecting flights, you only need to get retested before boarding connecting flights if:
- You planned an itinerary incorporating one or more overnight stays en route to the US. (NOTE: You do not need to be retested if the itinerary requires an overnight connection because of limitations in flight availability.), OR
- The connecting flight is delayed past the 3-day limit of testing due to a situation outside of your control (e.g., delays because of severe weather or aircraft mechanical problem), and that delay is more than 48 hours past the 3-day limit for testing.
If the initial departing flight in your trip is delayed past the 3-day limit of testing due to a situation outside of your control (e.g., delays because of severe weather or aircraft mechanical problem), and that delay is 24 hours or less past the 3-day limit for testing, you do not need to be retested. If the delay is more than 24 hours past the 3-day limit, then you will need to be retested.
If the connecting flight in your trip is delayed past the 3-day limit of testing due to a situation outside of your control (e.g., delays because of severe weather or aircraft mechanical problem), and that delay is less than 48 hours past the 3-day limit for testing, you do not need to be retested. If the delay is more than 48 hours past the 3-day limit, then you will need to be retested.

CDC recommends that travelers get tested 3-5 days after travel AND stay home or otherwise self-quarantine for 7 days after travel. Even if you test negative, stay home for the full 7 days. If you don’t get tested, it’s safest to stay home for 10 days. Always follow state and local recommendations or requirements related to travel.
All travelers (including those who have recovered from COVID-19) should remember to wear a mask, stay at least 6 feet apart from people who are not in your household, and wash their hands often with soap and water for at least 20 seconds after blowing their nose, coughing, or sneezing and before eating. Travelers should look for symptoms of COVID-19, and take your temperature if you feel sick. Anyone sick with symptoms of COVID-19 should self-isolate and delay further travel.
For more information, visit After You Travel.
At this time, CDC does not have a testing requirement for outbound travelers, but recommends that you get tested with a viral test (NAAT or antigen) 1-3 days before you travel internationally. Travelers should check with international destinations for their entry requirements.
People who have recovered from COVID-19 can continue to test positive for up to 3 months after their infection. CDC does not recommended retesting within 3 months after a person with COVID-19 first developed symptoms (or the date of their first positive viral diagnostic test if their infection was asymptomatic). Even if they have recovered from COVID-19, people who develop symptoms of COVID-19 should not travel and should seek care for testing and evaluation. This guidance may be updated as additional information about people who have recovered from COVID-19 becomes available.
CDC does not reimburse and is unable to help travelers get reimbursements for travel expenses as a result of canceled or delayed travel because of COVID-19 or testing requirements for air passengers flying to the US. While some companies may base their policies on CDC’s travel recommendations or requirements, each company establishes its own refund policies.
In some cases, trip cancellation insurance can protect your financial investment in a trip if you need to change your itinerary in the event of an international outbreak. Visit CDC’s Travelers’ Health website if you would like to learn more about travel insurance, including trip cancellation insurance.
CDC is not able to reimburse travelers for COVID-19 testing fees. You may wish to contact your insurance provider or the location that provided your test about payment options.
Aircraft Operators/Airlines/Crew FAQ
This order applies to all flights, including private flights and general aviation aircraft (charter flights). Passengers traveling by air into the US are required to have proof of testing regardless of flight type.
Yes, the Order applies to all air passengers arriving from foreign countries.
Crew members on official duty assigned by the air carrier or operator that involves operation of aircraft, or the positioning of crew not operating the aircraft (i.e., on “deadhead” status), are exempt from the requirements of the Order provided their assignment is under an air carrier’s or operator’s occupational health and safety program.
Crew members traveling for training, commuting to or from work, or for business reasons not associated with the operation of the aircraft are not exempt from the testing requirement. Nor are crew traveling for personal reasons, such as leisure travel.
In a positioning or “deadhead” scenario, the crew member is on the “clock” and their time and movement are directed by the air carrier either into, from, or between operational assignments. On the other hand, “commuting” to and from locations where official duty begins and ends is considered personal travel. Crew would not be exempted from the Order when they are in a commuting status.
For the exemption to apply, the occupational health and safety program must follow industry standard protocols for the prevention of COVID-19 as set forth in relevant Safety Alerts for Operators (SAFO) pdf icon[PDF – 7 pages]external icon issued jointly by the Federal Aviation Administration (FAA) and CDC.
Other persons, such as maintenance personnel or contractors, may also be exempted if:
- Their travel is for the purpose of operating the aircraft or ensuring the safety of flight operations; AND
- The air carrier extends its occupational health and safety program to cover these individuals and ensures these persons follow the protocols contained in SAFO and CDC guidance; AND
- The travel cannot be planned with sufficient time to enable the employee to take a COVID-19 test and obtain the results before the operational travel.
Air carriers or operators who assign their crew to travel in an official duty status (i.e., position or deadhead) on another air carrier should coordinate with that air carrier regarding their crew member’s eligibility for an exemption from testing.
CDC expects that air carriers or operators will determine whether their employee’s travel meets the requirements of the exemption. CDC also recommends that crew travel with an official statement (paper or electronic copy) from the carrier or operator that the employee’s travel meets the requirements of the exemption.
Operators of aircraft that are not operating under an air carrier’s or operator’s occupational health and safety program as described above are not exempt from the requirements of the Order.
Official travel by federal law enforcement officers is exempt from the requirements of the order if:
- Federal law enforcement is carrying out a law enforcement function (e.g., for security purposes) on the aircraft; AND
- the urgent need to travel does not allow time for testing
CDC expects that federal law enforcement agencies will determine whether their employees’ travel meets the requirements of the exemption. CDC recommends that employees travel with a copy of their travel orders and a signed statement (paper or electronic) from their agency stating that the employee’s travel meets the requirements of the exemption.
U.S. Department of Defense (DOD) personnel, which includes military personnel and civilian employees, dependents, contractors (including whole aircraft charter operators), and other U.S. government employees traveling on DOD aircraft or official DOD travel orders are exempt from the requirements of this Order, provided that such individuals are observing DOD testing requirements and recommendations described in DOD’s Force Protection Guidance Supplement 14 – Department of Defense Guidance for Personnel Traveling During the Coronavirus Disease 2019 Pandemic (December 29, 2020) including its testing guidance.
DOD whole aircraft contract charter operators are also exempt from the requirements of CDC’s order when transporting DOD personnel including military personnel and civilian employees, dependents, other US Government employees, and contractors traveling under competent orders and observing DOD precautions.
CDC expects that DOD will determine what is considered “official travel orders” that would meet the requirements of this exemption. CDC recommends that DOD personnel traveling on non-DOD aircraft carry their official travel orders with them and present to air carrier/operator or public health authorities if needed. DOD personnel, including associated personnel who are traveling on non-DOD aircraft and not on official travel orders, remain subject to CDC’s testing order.
See Safety Alert for Operators pdf icon[PDF – 1 page]external icon for the relevant guidance issued jointly by the Federal Aviation Administration.
At this time, the attestation form is not available in other languages. Airlines and aircraft operators may use a third party to provide translations of the attestation. However, the airline or aircraft operator is responsible for ensuring the accuracy of any translation. The airline or aircraft operator may not shift this responsibility to a third party.
Air carriers and operators must ensure that the attestation is submitted by each passenger or an authorized representative before the flight’s departure. Boarding processes must incorporate a process by which either a physical signature, an authenticated digital signature, or an electronic system that uses unique identifiers to ensure the person filling out the electronic attestation form is the passenger or an authorized representative. For example, similar methods to those used to verify the identity of a passenger using a pre-boarding kiosk or an air carrier’s or operator’s website or app to obtain a boarding pass could be used to ensure that the passenger or authorized representative is the individual completing the attestation.
Alternatively, the air carrier or operator can use authenticated digital signatures (e.g., DocuSign) or an electronic version of an attestation that ensures only the individual passenger, or their authorized representative, has access to the data entry process (e.g., after keying in username/password or other identifying and/or itinerary-specific information as part of the pre-boarding or check in process).
Either method is acceptable if the air carrier or operator can be reasonably certain that the individual, or their authorized representative, is the only person that has access to the data entry process required to submit the attestation.
Yes, airlines/aircraft operators may use and retain an attestation only in a foreign language.
At this time, there is no alternative form of attestation. Airlines and aircraft operators must use the current attestation without alternation.
Operators of private flights and general aviation aircraft must maintain passenger attestations for two years, per the Order.
No, passengers must show a copy of their test results to airline employees or the aircraft operator before boarding, but the airline or aircraft operator does not need to retain copies of test results.
For transporting patients that have tested positive for COVID-19, operators must adhere to CDC’s Interim Guidance for Transporting or Arranging Transportation by Air into, from, or within the United States of People with COVID-19 or COVID-19 Exposure.
