@Jim doe I have. it was seamless. I first applied & paid through this link : https://tsaenrollmentbyidemia.tsa.dhs.gov/programs/precheck?utm_campaign=WT-TSA+%7C+Enrollment+-+TIERS+1+%26+2+(NEW)+MX_Conv+%7C+POR-00349-25-00000077&utm_source=google_ads_search_direct&utm_medium=Precheck+-+T1&utm_term=tsa%20precheck&gclsrc=aw.ds&gad_source=1&gbraid=0AAAAAC_oJjJ0EJOY92myyzYn8Z7c25eEw then looked for a location close to my home address online and set up an appointment, you have to go with your Greencard, ID and SSN, they will take your fingerprints & passport photo then you answer some questions. it’s really quick. Approval is what takes time, could be weeks or months. I applied 3/2/25 it was approved 4/25/25. Once approved, TSA will issue you a Known Traveler Number (KTN) for you to use when making flight reservations. you will be able to see your status here: https://tsaenrollmentbyidemia.tsa.dhs.gov/workflows?workflow=service-status
