US Immigration from Turkey

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?

Hello! I have question which one is the best to attach with my file as proof of income account transcript or return transcript

i am pretty sure this question has been asked before. I'm still getting a feel for how this website works.

But I am finishing up with the k1 visa. I am the petitioner. To my understanding, I know that everything needs to be wet signature. However, How do I go about this having my fiance sign documents if he is abroad? Will Docusign work?
