US Immigration from Malaysia

What is the worst that can possibly happen if someone who is applying for AOS from a K1 visa has the waiver for vaccines denied?

I'm asking this theoretically because we're not to that stage yet. But I'm worrying about this so trying to calm my fears.

I've sent two inquires to the USCIS myself the wording on the responses I got basically said my case was waiting adjudication. I just got a response from the inquiry my senator did for me, and the wording on that one sounds more hopeful. It said that our case has been assigned to an officer and it's being reviewed and to expect correspondence soon. Does this mean that our case is making progress, or do they just give better sounding responses to congressional inquires?

Hi, I ve applied F2B visa for my daughter middle of last year.

She has 7 years left on her US tourist visa. Can she come for a visit, probably a month or two, while her application is on-going? Would it affect her application in any way?

Hello,

My I-140 (EB2-NIW) was approved by USCIS at July-5-2022, and on the approval notice it was mention that it will be forwarded to NVC. Until now (08/31) , NVC had not contacted me to give me my case number or invoice me. Do you know what is the timeline to get your case number and invoice from NVC? Should i contact the NVC? From NVC's website I can see they are responding very slowly.

please let me know what should I do as I am quite nervous.

My fiance and I applied for a k1 visa September 2021. We've been waiting 11.5 months for noa2. Now we're wondering whether we should just get married and switch to CR1. Would he be able to legally work sooner with CR1? Would he be able to spend much time visiting here with his b1/b2 visa while waiting for the CR1 to be approved? Does he have to wait a certain amount of time in between his visits? How likely would a k3/k4 visa be approved while we're waiting for spousal visa to be approved?
