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

I'll be here for the next 5-6 hours. As usual, there are countless topics given the rapidly changing immigration landscape and I'll be guided by whatever you're concerned with. Please remember that I can't provide legal advice on specific cases because I won't have access to all the facts. Please stick to a factual discussion in your questions and I'll try to do the same in my answers.

Edit: I am taking a break now and will return later this afternoon/evening to respond to any comments and answer any questions. Thank you everyone for a great and engaged AMA so far.
