They’re strict. I grew up here and kept having to get more data - college transcripts, address records, and finally when I dug up my 1974 passport that wasn’t renewed until 2006 they got the point that I never left the US for over two decades. No passport no travel.
You’re gonna have a tough, tough interview. I was pretty mad after mine. Had to call “the dude from the back” to get that application in.
Employment letters are going to get tossed. You will need physical proof of address and employment like tax returns and W2’s. That crazy lady even implied “you could have been out of the country between semesters” because my data was spotty - until I asked her “how without a passport?”. That did it.
School records, address records, employment records backed by W2’s would be a good start. Try pulling driving records showing active drivers licenses, etc. You need a stack dude or they’re going to send you out to get it.
