US Immigration from New Zealand

Hi everyone! My apologies if this has already been asked/answered or if it sounds dumb.

I came here on a K1 and am about to adjust my status. I'm also looking into how to get a bank account and/or driver's licence shortly. However, I see that for both of these things they require proof of address. I'm a bit stuck with this because, typically proof of address is a bank statement, government-issued mail or some kinda bill - I don't have any of these. I have an SSN - not sure if I can use some part of that for it. Any ideas on what I can do? If I get put on my husband's lease can I then use something from that as a proof of address?

Let me know!

This is probs a dumb question but I've seen some conflicting information!

I've read in a few places that all K1 AOS packages should be sent to the Chicago lockbox. Idk if that just used to be this case but this page says that for me (living in Colorado), I should send mine to the Phoenix lockbox.

Is this the case? Or do the K1 AOS's count as something slightly different? Let me know!

Hi everyone!

I know I need to provide various passport-style pics with my AOS application, and can use the ones I got taken for my K1 interview.

I no longer have the actual physical pictures that I got printed (the ones that are on proper photographic paper), but I have the digital version. Can I just print this on normal paper?

Hi everyone! Quick question as I'm filling out form I-765:

In part 2, question 18a/18b, it says,

"List all countries where you are currently a citizen or national."

I put New Zealand in the first box since I was born there etc. But I also have an expired British passport that I got when I was a baby, since my Mum was born in Scotland. Should I also put the United Kingdom as a place that I am a citizen/national?

Hi everyone!

I got married a few days ago and have a question about changing my surname. My husband technically has two last names but only uses both on legal/official things. If I take his last name, do I also need to take both, or can I just take the first (main) one?
