You will want to request a "TECSII Primary Query History" from CBP. They are doing a much better job of responding to FOIAs than they used to - the current administration has made a priority of clearing what was quite a nasty FOIA backlog.

Mine had both entries and exits by air, as well as a bunch of places I visited on an Alaska cruise (which was kind of a surprise, since some of the ports were US-to-US segments - maybe the ship went through international waters?).

I would recommend that you allow a couple months and send your request by certified mail. However, they also seem to respond to emails sent to [email protected].

Have fun...
