US Immigration from New Zealand

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?

Hi all!

I've been looking into putting together my AOS package for when I'll be filing in about a month. I've seen that they say ideally to attach a certified copy of a birth certificate. Is this a necessity? Or does it not matter as long as the copy includes all the things they need to see? I'm just a bit concerned that it'll take too long to get my birth certificate certified if I have to somehow do it in New Zealand when I have the certificate with me and need it done within 2-3 weeks. I just don't want an RFE!

Also does the marriage certificate need to be certified too? I'm not sure how I'd have time to do that so close to the 90-day mark.

Kind regards,

Rosalea
