US Immigration from Pakistan

I am U.S citizen, my parents are in Pakistan I filed their immigration. we received notification in Jun 2022 that all documents are accepted and approved we should wait for interview call from Islamabad. we have been waiting since then. is there any timeline how long does it take ?

any help is appreciated.

While filling out I-485, should I fill out I-131 - Appliation of Travel Document, since there are no travel plans? What is the advantage of filling out with I-485 AOS?

Which category I should select for Parent who is already in US on B-2 VISA in Form I-485 item # 27?

I have already applied i-130

Hey. My Fianc (petitioner) have applied for K1 visa for USA. We are first cousins. My fianc lives in a state that doesn't allow cousin marriage. We have signed an affidavit that states that we are planning to get marry in a State that allows cousin marriages and won't break any law. Has anyone gone through same situation and still got the visa? Or do you know some

one else how faced same situation like us. Any suggestion or advise will be appreciated. Thank you
