Most of us learned how to use the TSA website for foreign nationals seeking flight training when it was the Alien Flight Student Program (AFSP) website. Recently the FAA has made some broad and sweeping website changes, the TSA is no different. So a lot of the information that used to be very easy to find on the FAQ page when it was the AFSP site has been moved and is seemingly nowhere to be found. It is still available, though. In fact, the current Flight Training Security Program's FAQ page links directly to it…but it's not clear that the expanded FAQ information is what you're clicking on.
That page is extremely helpful to candidates looking for information on the process because there is a section dedicated specifically to what they need on this “hidden” FAQ page. You can check that info out here:
