We will need to review the previous flight experience and validate the qualification of the candidate for flight training. There is a regulation that requires identifying US us citizenship prior to beginning certain flight training activities. For non citizens the candidate needs to go through a process with the TSA. Here are some of the highlights and links. Please contact us with any questions.
Before a U.S. citizen can begin flight training toward an initial FAA pilot certificate, recreational, sport pilot, or private pilot certificate; instrument rating; or multiengine rating, a CFI must verify citizenship.
Other requirements apply to non US Citizens. See the TSA site: FTSP
