US Immigration from Norway

Hi. Excuse me if I'm not doing this the right way, it's my first time posting something on here. I entered the US on a K1 visa in september 2024, got married in november and filed for my AOS and EAD early December. Yesterday I finally got my EAD approved. I'm interested in continuing my education here and I have been looking into different universities. Do any of you know whether or not I can study while I'm waiting for my I-485 to get approved or do I have to wait until then?

Is this still the right place to post this? Im not sure. Anyway.

I went to the Swedish embassy page to continue the application process, and they had me make an account with them. However, I am confused on two fronts:

1. They made a big deal about my name. I have a norwegian letter in it, so I cant use my actual name. The problem is that in my ftp letter they write it with one A, but in my passport it both says the norwegian letter but at the bottom with a bunch of numbers it is replaced with two As. An is basically two As so that makes sense, but since nvc has my name with an A should I also do that? In the 129f application we wrote it with an A plus in the section where you can add special characters we spelled it correctly. My ESTA however, spells it with two As..

2. I started off with an account and it asks for my country. So I picked Norway, because it isnt asking for where I want my appointment. But then when I managed to sign in it is stuck on Norway so now I dont even know if I can make an appointment? This is very confusing to me. X_X I am assuming this should be Sweden, since that is where I have to interview?

I started off making an account, writing the name like the nvc letter and picking Norway. Then I made another when I realized the mistake. I used a different email, but it might be on file as my second email? Now I cannot log in at all...

Should I make a third account? At that point I might need a new email. What a mess. X_X Luckily I havent put in my passport info or anything yet.

I feel like I have asked this before, but probably a year ago and I just want to make sure I do what I need to here.

I am currently doing a K1 with my fiance. I have two kids from a former marriage, who have an american dad. Their american passports and snn are on the way in the mail after an appointment a few weeks ago.

When I finish all the visa stuff and I am ready to move, what do I need to do for them? I mean they are kids, and I have a custody agreement from their dad stating I can move with them. But once we get to the US (or at the POE idk) I assume I have to notify someone? Is it as simple as just a change of address for them?

Appreciate any help.

For those of you who came to the country on a K1 visa, how did you get a wedding together in less than 3 months? We are considering doing a quick and easy one without guests and do a bigger celebration later on, maybe in a country where our friends and family can meet in the "middle", but I would still like to do /something/ once I move over there. From what I have seen, most people plan their wedding for months and months or even years, and while you can think about attire and plan some of the things, anything that involves booking something is out of the question until you have that visa in hand. And by then you dont have that much time anymore.

Any experiences are welcomed.

So while wating for NVC to work on our case I am getting my ducks in a row! Yesterday I reached out to the police to ask how to attain a certificate. Luckily they offer one to use abroad in English, so that is pretty straightforward. What they could not answer me was how long it is valid, they just told me that is probably up to the US embassy. The process only takes a couple of weeks, but I am trying to prepare as much as possible, so I was wondering how long I should wait to order it? What is the expectation from the embassy? Unless you get the certificate the day you have your interview it will never be truly up to date, but still, what should I plan for here?
