Civil surgeons must follow specific identification procedures, prescribed by the U.S. Department of Homeland Security (DHS), to ensure that the person appearing for the medical examination is the person who is actually applying. The civil surgeon is responsible for the entire examination, including chest radiographs, when required, and necessary laboratory procedures. The civil surgeon is also responsible for reporting the results of all the required tests and consultations on the prescribed forms. The civil surgeon is not responsible for determining whether an applicant is actually eligible to adjust their status; that determination is made by the DHS officer after reviewing all records, including the report of the medical examination.
