Depends on how much due process they’re willing to allow.

I’m very white, so that’s something.

I almost always have my drivers license on me, that should be worth something. However I’m pretty sure my state gives out licenses regardless of immigration status. Also, while I paid for RealID, I didn’t get it

In case due process and constitutional rights were allowed, I have a passport and may be able to dig up a birth certificate. You can’t really do any better although I believe they’re already ignoring that
