I'm Peter Roberts, immigration attorney who does work for YC and startups. AMA

I'll be here for the next 2.5 hours and then again at around 11:30 am PST for another 2.5 hours. As usual, there are lots of possible topics and I'll be guided by whatever you are concerned with. Please remember that I can't provide legal advice on specific cases for liability reasons because I won't have access to all the facts. Please stick to a factual discussion in your questions and comments and I'll try to do the same in my answers!
