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

I'll be here for the next 6 hours. As usual, there are countless possible topics and I'll be guided by whatever you're concerned with but as much as possible I'd like to focus on the recent changes and potential changes in U.S. immigration law, policy, and practice. Please remember that I am limited in providing legal advice on specific cases for obvious 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 responses. Thank you!
