US Immigration from Laos

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?

Hello I was wondering will my AOS get recheck again 1 year later or new fiscal year my wife pass her interview as of Feb 2021 but there a visa ban in Laos so there is no issue of visa and it coming to a new year when they do issue a visa will they check for a AOS again ive change Job and do not make as much as before thanks in advance.

243(D) sanction laos, so they are not issuing k1 visa at this time in laos and also says 365 days if i choose to wait before scheduling a interview? so i can wait at least 1 year before it actually expires? should i wait until they lift the ban on visa in laos? or schedule the interview now?

Is there a deadline for I-129f after getting approved from Uscis? I-129f approved 3/12/201 then sent to nvc to u.s embassy but i did not hear anything from u.s embassy until 9/1/2021 which is 6 month passed.

is there a deadline after that to prepare the interview/exam etc.?
