Civil Surgeon
A medically trained, licensed and experienced doctor practicing in the U.S. who is certified by USCIS (U.S. Citizenship and Immigration Service). These medical professionals receive U.S. immigration-focused training in order to provide examinations as required by the CDC (Center for Disease Control and Prevention) and USCIS. For medical examinations given overseas, please see Panel Physician.
IMPORTANT: medical examinations will not be recognized if they are given by a doctor in the U.S. who is not a Civil Surgeon; please make sure that your appointment is with a Civil Surgeon or your results and documents will be invalid.
