Question: how do you know if you are eligible for tsa precheck?
Answer: As a law-abiding* US citizen, US national, or Lawful Permanent Resident (LPR), you may be eligible for TSA Pre-Check. In order to apply, you must pay the non-refundable fee of $85, provide information that would allow the TSA to conduct a background check (i.e. fingerprints, SSN, etc.), and visit an enrollment center.
