US Immigration from Pakistan

So my husband and I filed the NVC part and are waiting on their response but I was curious once they approve everything how long will we be waiting for his interview? His interview will be in Islamabad, Pakistan. My sister in law's sister in law ( sorry for the confusion) is not a US citizen and applied for her husband and has been waiting over a year for an interview. I'm hoping my husband will get his right away since I am a US citizen. I'm just curious about other people's timelines

We have interview for I-485 on 13 Apr 2022. My sponsor (wife) didn't file tax for 2021 bcz we want to foling jointly and waiting for my SSN. She filed tax extension for 2021 and got deadline til OCT 2022. We have tax extension paper from Turbo tax and her W2. I want to know will it be problem in my interview ? Or extension is acceptable with USCIS? Any expert advice or suggestion will be highly appreciated.

Hello. I have a 10 year Permanent Resident card along with a valid Texas Driver License and a Social Security card that says VALID FOR WORK ONLY WITH DHS AUTHORIZATION . This was issued after I had my EAD. have not got a chance to update my Social Security Card to the unrestricted. Social Security Administration being closed due to COVID-19.

Do I present my Permanent Resident card to my employer for 1-9 or Texas Driver License and Social Security Card since they may also run it on E-Verify?

once NVC complete the case how long it will to to get interview call in ISB Pak

Does USCIS normally call you over the phone? I was given a 'decision couldnt be made' paper slip in my n400 interview about a month ago. My online USCIS account still doesn't show any updates but I received a phone call claiming to be from USCIS and said I've an Oath ceremony in about a month. I still don't see anything in the USCIS online account so I'm left wondering if the call was legit. They just said my applic was approved and shared with me the location/time for oath ceremony.

Is this a normal thing for USCIS to call up about oath scheduling?

Cheers
