I am in Stockholm. DH is from the North though (Umeå) Is Luleå your Oh's home town?
It must be a challenge living here without a personal number! I have been here since March this year and my personal number was here within two weeks of sending in my application, which was nice. I guess you are planning to study Swedish once you get it? I did that, so I speak a little bit now. SFI is REALLY fun and I highly recommend it as soon as you get your personal number. Swedes often have a bad impression of SFI and will recommend you go to some place where you have to pay for classes. In my experience, it is just a stereotype, and as long as you get a good teacher your class will be great!
Feel free to message me anytime. I can also give some tips on the SFI and SAS system (which can be confusing) once you get your personal number and are ready to study. On the other hand, my tips might not be useful because I think different kommuns set up their programs quite differently.
Good luck getting your BFP!!!
