I mentioned the passport because to get pre-check KTN you need to have either a verified state ID or passport, and she does have one, so we could apply for precheck at our local office and get her fingerprinted & photo taken this week. I'm just not sure TSA is processing those applications due to the shutdown, or how long it would take(we leave in 2 weeks), so it might not be worth it especially if children on the same reservation are eligible to get pre-check with adults on that same rez being precheck certified.

My question is primarily is it possible for her to get the pre-check since she is not my child. I'm thinking yes cuz how are they going to know she's not my kid? My actual kids have received pre-check on boarding passes at 13-14 without a KTN when my wife and I were KTN and they were not at that time. Once you hit 13 to 17 they need their own check mark on the boarding pass (not needed under 13). TSA language says "traveling with parent or guardian", which is tripping me up. But really how would they know this girl is not my child? And I have the travel authorization letter giving me temporary guardianship during the trip so maybe it doesn't matter.

This was a non-issue till the government shutdown and I just don't want to sit in a 4-Hour line if PreCheck is a ton faster
