G-325-A ; have some questions about the "Previous Addresses"

[sephiroth144 0]

Okay, have a somewhat specific question, regarding my g325a...

(Quick backstory, we got married a few months ago in the US- my wife is in the country on an F-1- figured no reason to wait to get this juggernaut rolling...)

Filling out the G-325-A (for myself/the citizen one), in the previous addresses, aside from the home we live in now, is one previous address, (the one recently moved out of). However, when I originally moved in, (was a sublet, but didn't know it was going to work so well), I got a post box that I've used for EVERYTHING- as in Driver's License, Banking, Voter's Reg, Veteran's Affairs- absolutely nothing is tied to the "where I sleep" address. This "Sleep Address" isn't on my credit report or anything that I could find. And flipside, not anything that could prove that it is indeed my address, (no utilities or the like).

So, I'm wondering if I should just use the address I always use? Because aside from actually going to the site physically, that post address is the real one.

.... In case the last part of the large paragraph is unclear- proving my residence address is nigh impossible, (i.e., when I went to get a credit union account some time ago), I couldn't prove I lived there (at the "sleep address"). However, went back a few days later, talked to someone else, using the post address- walked out with a temporary ATM card for the new account in my wallet.
