I have been using a recruiter which has seemed legit: good website, reviews, fb pg, etc. I have submitted all of my documents for the E2 visa reservation number so I can go to the consulate here in the US. So far everything is playing out as expected. The issue is that I just received an email with the attached document asking for my social security number. I have not seen anything posted anywhere that this is to be expected. Feedback on this would be greatly appreciated. Was this requested of anyone else? Is this a scam?
