I will answer your questions from I129F as that is my case for my wife as well.
-I am divorced since Nov 24 and was in separation/divorce process originally when we met, will it affect this at all?
It should not as long as you both were legally free to marry at the time of the submission of your I-129F
-I hear about the timeline of k1 where recipient is not able to work, but able to come here, but being that her salary is low I’m not sure it makes a difference if she can’t work temporarily. Would she be able to attend any school on k1 or do odd jobs for cash like babysitting?
Absolutely NOT, she cannot work till approval of her work permit (or green card)
-if she gets k1 could she go back to Indonesia or travel to any other country during the initial 90 day period and get married there? As she wants to have family party in Indonesia
-she is Muslim so if we officially marry overseas it would have to be somewhere like Singapore i assume
The K‑1 visa is single entry visa, If she leaves before getting Advance Parole (or a green card), she normally cannot re-enter
A K‑1 requires you to marry in the US within 90 days, If you marry abroad instead, the K‑1 route dies and you’d switch to a spousal (CR‑1/IR‑1) case.
You can always Marry civilly in the U.S. for immigration, then travel for a reception once she has Advance Parole or her green card.
We are also muslim, she came here we married here and had a party there and after her green card we went abroad and had a party with her family as well.
I took a big chance with K1 during covid times, somehow it worked out but if given a choice now I will never go K1 route, and this is 100% based on my flawless experience of the process. I 110% blv that CR-1/IR-1 is a much stronger case, you basically hit the ground running. K-1 and CR-1 timelines are also debatable at this point in time.
Good luck in your journey, we are rooting for you and hoping that you get together with your loved one sooner than later.
