YSK: How to document that you are a US citizen
https://www.usa.gov/prove-us-citizenship
The most common way to show that you are a US citizen is to show a passport. However, only about 50% of US citizens have a passport.
An alternative to a passport is a Certificate of Citizenship.
Certificates of Citizenship and Naturalization show proof that someone is a U.S. citizen. The website https://www.usa.gov/prove-us-citizenship shows how you can get or replace these documents.
Prove your citizenship: born in the U.S. with no birth certificate. If you were born in the U.S. and have no birth certificate, learn how to get documentation to prove you are a U.S. citizen.
Prove your citizenship: born outside the U.S. to a U.S. citizen parent. Prove your U.S. citizenship without a birth certificate if you were born outside the U.S. to a U.S. citizen.
What about a “Real ID” drivers license?
While a regular license makes no claim about citizenship, id expect “Real ID” to only be obtainable by citizens
That’s what I was thinking and wondering too
Yet if you’re homeless living in your car you cannot get one which means you cannot go into the social security building
Real ID proves legal presence in general iirc. E.g., permanent residents can get Real IDs
