US Immigration from Laos

Hi, I'm struggling to make sense of the vaccination requirements and getting different answers.

My spouse said he was only missing one shot since he didn't have time to complete it. But it looks like its several shots.

Does anyone know what are the vaccine dosages/series requirement per vaccination?

I think I screwed up!

My spouse and I tried to apply for his social security today and that's when we were informed his K-1 visa expired. That's when I realized I lost track of my own timeline and didn't file for his AOS yet. We did get married and got a marriage certificate.

Is this gonna be an unforeseen issue when we file for his AOS?

This has taken a toll on my mental health - please only comment with helpful information. Thank you!

Edit:

It's been a month outside of the 90 days.

My fiance had his K-1 approved. We are leaving from Bangkok to the US on April 13th.

Other than the K-1 visa stamp on his passport, what else does he need to bring with him to customs when he gets to the US? We are going through SFO.

hello, do we need criminal background certificate letter from police

So things are moving much faster now since the sanction on Laos was lifted.

My fiance and I finally got our interview appointment and realized we need to renew the I-134 since 2020 was a long time ago. On the new I-134 form, it says the form expires on 10/31/22. Our interview is on 11/3/22 - will this be an issue?
