My wife came to US on H-4 initially and applied for H-1B. She has got RFE asking for more project details. She got one job offer meanwhile and her employer replied for RFE also filed separate Amendment petition with new job offer details. We have got approval for H-1B without I-94 details. Shall we expect I-94 once the Amendment process is approved?

Currently my I-140 is approved and now for the I-485 I need to present date of birth certificate. Problem is that DOB on certificate is correct and on all other documents including school, college, and passport and in all US records it is in correct. It started with wrong DOB in 10th certificate which was used in college, passport and finally all US documents. Now I went through all the channels and found the ways to change in passport and in all US documents. Question is what legal problems I should be prepared for and how it impacts my US records once it is changed. I am in US for last 7 years. I need to take decision on this as if it is worth doing it or just go back to India and may be forget about GC for this time. Really appreciate you taking out time for this kind of questions.

My H1B petition got approved through my existing employer and became effective 10/01/14 (I was on F1 OPT before). Where am I eligible to go to for doing first time H1B stamping, other than my home country (Russia) – can it be done in Canada, Mexico, or other countries? I have Masters from an American university, and over a year of working experience in the US. Also I’ve heard that starting June Canada has suspended doing first time H1B stamping, can you please provide any clarification, and also could you please advise what all options are available to me?
