US Immigration from Turkey

I have a question about my k1 application after my case was approved with USCIS on October 8, 2021, It went to the NVC and then I got an email from the NVC that my case went back to the USCIS on November 24, 2021 for review. Is that normal? and how long will it usually take to go back to the NVC?

Me and fiance started our k1 visa journey. I was wondering can he apply for turist or student visa while we are waiting for our K1 visa? We will not get married. I cannot visit him due to my work so he would like to visit me.

I know this has been asked multiple times. but i couldn't. find the specific question I was looking for. But just out of curiosity, are we allowed to take our own passport photo with our own phone? Can someone just take a picture of me in a white background and I can just change the size later? Or do i actually have to go get a passport 2x2 photo?

I'm applying for a tourist visa, and for some reason it is not asking me the previous employment/education/training. We just filled the form for my partner, and he was asked to fill that part. I know this is a bug, and there is a work around to make it visible and actually fill it online. Does anyone know/remember what to do?

I was just wondering, can the beneficiary apply for any kind of visa to visit petitionery while k1 visa process is on going?
