"If you're not a U.S. citizen, the DMV will often limit the validity of your Real ID to match the expiration date of your lawful presence or immigration status. That could be your visa expiration or the end date on your I-94 or other documentation (like an EAD or green card)."
It's very easy to identify whether a person is citizen or not. Policemen all have laptops in the cars. Typing in SSN, immediately know everything about you.
I knew this gonna happen 20 years ago. So I decided to quickly turn from green card to naturalization. I joined the Army and got citizenship within a year. It's never safe to be a permanent alien.

有個外國麵孔的，現在的確要小心了，ICE會隨時去餐館超市檢查的，也會路上攔車檢查的，看到他們認為是可疑的就會要求出示證件。
