After searching through the forums, I wasn’t able to find what I felt was an accurate analog to my situation.
A few days ago, I went to my local NIA to update my ARC and didn’t think anything of them holding onto it while I waited the two weeks. I just realized, however, that I was wanting to open a new bank account (or just use some banking services with the post office).
From what I understand, normally, you need your ARC or an RIN with your passport. What would be the best action for my case right now? Do I need to go back to NIA and get a copy of my old ARC? Copy and RIN (since I’ve heard banks aren’t always happy with just a copy)? Could my NHI card with the ARC no. work?
