There are many people who are legally present in the US without a social security number and a driver's license.

I would think that a valid passport, with a visa if required, would be sufficient for a non-US citizen.

Citizens do not carry such identifications, thus the lack thereof indicates what?

Unless contradicted by treaty, every non-resident alien has to have a passport, a visa, and a I-94 card (says how long they are allowed to stay pursuant to their visa). For example a B1/B2 visa can be good for 10 years but each trip can only be 3 -6 months max.

The consular matricula is an underhanded and illegal means of bypassing US/mexican treaty.
