For fellow Americans living in cities where ICE is active, many people, especially those of Hispanic descent, are already carrying around passports on their persons at all times because they’re rightfully afraid of being forcibly disappeared or deported to some random South American country.
A passport card can be obtained for $30 from the Department of State. It is considered exactly equivalent to a passport within the US, but it’s the size of a credit card. It is a valid travel document for land and sea travel within North America and the Caribbean. It also counts as a Real ID. The card is good for ten years.

Do not do this if you are transgender or have an X gender marker. They will cancel your passport and tell you to apply for a new one with your sex assigned at birth.
They can still just detain you because they can steal it or say there’s no way to verify your passport or ID isn’t fraudulent without further investigation so how about you spend a few days or weeks in jail while we sort it out 😉
But yes it is still a good idea and won’t hurt
