What should I do if I hold a foreign medical certificate or endorsement and I want to exercise pilot privileges in the United States?
You must have the validity of the foreign license and medical certificate or endorsement you hold verified by the Civil Aviation Authority that issued those certificates.
The FAA has devised a form entitled Verification of Authenticity of Foreign License, Rating, and Medical Certification (PDF). You must submit this information, along with a copy of the license you wish to have verified, to:
Airmen Certification Branch
AFS-760
PO Box 25082
Oklahoma City, OK 73125-0082
