Fiance is planning on bringing emails/chats/call logs and photos. Are these enough?

Hi. I am the beneficiary. We hired a lawyer to process our petition and we already got approved. Our case is already at the US embassy and I can already schedule for my medical and interview. However, when we asked the lawyer to send us the copy of I129f, I saw some errors. I have no children but the box was ticked that I have. Also, my passport details are blank. We are worried that this will affect the interview process. Any thoughts on this matter, please? Thank you!

My Wife's I-130/129 is currently being processed. We're waiting for the NOA-2. I'm considering applying for a new job and am curious about the ramifications it has during the visa process. I know the next steps are to provide employment status/financial numbers/previous tax records, etc the fun stuff.

Have any of you guys as a Petitioner changed employment (voluntary/non-voluntarily) during the visa process? How did it effect it? Curious if it's a good time to do it now or later. Any thoughts would be welcomed.

Hello guys i signed and dated my photo and send to my fiance is that okay if i dated before he send the package? or he need to update the date by putting (date) when he will send the package? Thanks for the help
