Civil Surgeons are designated by the District Director of the U.S. Citizenship and Immigration Services (USCIS). Immigration regulations state that each civil surgeon selected shall be a licensed physician with no less than 4 years of professional experience. A written request for Civil Surgeon designation along with evidence of the requirements should be directed to the appropriate USCIS office. CDC is responsible for providing the technical instructions to Civil Surgeons conducting medical examinations for immigration. The instructions, along with important updates, are available on our website: http://www.cdc.gov/ncidod/dq/technica.htm.
