49 CFR § 1552.7

No flight training provider may provide flight training or access to flight training equipment to any individual before establishing that the individual is a U.S. citizen, U.S. national, DoD endorsee, or candidate with a valid Determination of Eligibility resulting from a TSA-accepted security threat assessment completed in accordance with subpart B of this part.

To establish that an individual is a U.S. citizen or a U.S. national, each flight training provider must examine the individual's government-issued documentation as proof of U.S. citizenship or U.S. nationality. A student who claims to be a U.S. citizen or a U.S. national and who fails to provide valid, acceptable identification documents must be denied flight training. A list of acceptable identification documents may be found on the FTSP Portal.

To establish that an individual has been endorsed by the DoD to receive U.S. Government-sponsored flight training in the United States, each flight training provider must use the FTSP Portal to confirm that the endorsee's government-issued photo identification matches the information provided in the U.S. DoD endorsement available on the FTSP Portal. A DoD endorsee is exempt from the requirement to undergo the security threat assessment required by this part if the DoD attaché with jurisdiction for the foreign military pilot's country of citizenship has notified TSA through the FTSP Portal that the pilot may participate in U.S. Government-sponsored flight training.

To establish that a candidate has undergone a TSA-accepted security threat assessment, each flight training provider must use the FTSP Portal to confirm that TSA has issued a Determination of Eligibility to that candidate and that the determination is valid.

Each flight training provider must immediately terminate a candidate's participation in all ongoing or planned flight training events when TSA either sends a Determination of Ineligibility for that candidate or notifies the flight training provider that the candidate presents a security threat.

Each flight training provider must acknowledge through the FTSP Portal receipt of any of the following TSA notifications: Determination of Ineligibility; Candidate Security Threat; and Deny Candidate Flight Training.

Each flight training provider must notify TSA if the provider becomes aware that a candidate is involved in any alleged criminal disqualifying offenses, as described under § 1544.229(d) of this subchapter; is no longer permitted to remain in the United States, as described in § 1552.35; or has reason to believe the individual otherwise poses a security threat.
