The "green" card itself does have an expiration date (much like DL). It is just a matter of renewing and getting another piece of plastic. If I remember correctly it is valid for 10 years.apostate wrote:Permanent Residence status doesn't expire. At least it didn't for my family members who had green cards.
DPS does however do the special DL for temporary visitors with H1B and student visas, from what I have seen.
There is also something in the law where you have to be a resident for x months at a location before you buy guns if you have green card but are not citizen but I don't remember the details.
