HI,
I got approval for my H1B and I am going for stamping interview in next week at Mumbai center. Is it posssible that it will get rejected during stamping? If yes, what could be the reason and how can I prepare myself so that it will get approved.
The visa officer will verify all the documents, if your documents are in line with USCIS guidelines and are accurate then you should not worry about rejection. Usually if they find any inconsistencies they would issue an RFE first. Upon answering to that RFE if they are not sattisfied they can ask USCIS to revoke the petition. But again if your documents are accurate then you should not worry !
