It just means the Cal license is acceptable for access to federal facilities because they distinguish between citizens and criminal invaders. New Mexico licenses don't.
I still don't understand. If a Cal license is acceptable for access to federal facilities, the person that got it had to provide proof of citizenship or is present in the US legally. Is that the case?
In New Mexico, all illegals have to do is provide two proofs of residency (e.g. two utility bills with an address on it, for example) and proof of foreign country birth or, for Mexican citizens, a Mexican Consulate ID card. No other test identifying them as to immigration status is required. And no indication is present on the license as to what ID was presented.
