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

An immigration lawyer answered Hacker News questions on U.S. visas, green cards, and citizenship, with a focus on startup and Y Combinator-related cases.

Topics included PERM labor certification, TN and H-1B visas, green card job changes, and how much workers can safely move between employers.

The discussion also covered Trump-era enforcement concerns, ICE risk, and the practical impact of the new $100,000 H-1B fee.

The lawyer said AI can help with basic research, but it remains limited for real immigration legal work and case-specific judgment.
