Hello, just wanted to share a Global Entry report. I applied last year (Boston) took a few months, but got it. This time I wanted to get my 18 year son into the program. He had just received his passport in the mail. We applied online--(Big mistake--paid by e-check which adds 5 days) in early August. In about 10 days on 8/18 he was conditionally approved, 5 days after the e-check went through. I listed his employment as Student.
He has not ever moved so perhaps that made things easier. Perhaps the fact that dad is already approved made it go easy.
Anyway, as it turns out he was flying today with a 2 hour layover in IAH. I could see that IAH (the one INSIDER Terminal E) has tons of availability but they won't book less than 24 hours in advance.
I told him just to find the IAH office INSIDE the Terminal E sterile area. (It is near Ruby's Diner which is near the security checkpoint.) After a little confusion,
he didn't use the term walk-in and they slightly scolded him for not having an appnt, but they took him and now is (will soon be) officially approved. Total time 3 weeks max.
