So I was in the US last week and I called the SSA (1-800-772-1213 - don't even bother unless you are a very, very patient person) about the status of my SSN.
This was quite an interesting conversation, because I got my SSN back when computers were pretty crude, but yet to my amazement they had all the info about me in their system.
In the US for several years now they have had a system called: "E-Verify", which employers _may_ use to check the status of a SSN to see if the person is qualified to work in the US. Long story short, major employers check, smaller employers generally don't, although there is a Bill in Congress at the moment to make checking the E-Verify system mandatory for all employers.
What I found quite interesting about this conversation is that SSNs are automatically marked as "not valid for employment" based on the information keyed in by the person at the SSA when you apply for your SSN.
So basically, if you go in on a work permit, the person at the SSA types in the expiry date of your permit, and on that date your SSN becomes invalid in the "E-verify" system.
The problem here is that you might renew your permit, but your SSN is invalid - so if the employer checks the system, you will come up as unemployable even though you are. The impression I got from talking to them is that if you are still working for the same employer, this is unlikely to be a problem, because the employer is not going to repeatedly check the SSN validity (although they could, theoretically, depends on the employer, especially if you have a new permit).
However if you change employers, you could face a problem. I was advised that upon entry to the US on a new work permit, I should take my social security card to the nearest social security office with my immigration paperwork and have it re-activated. You cannot be issued a new social security number, as under Federal law each individual can only have one number (with some very limited statutory exceptions).
So the moral of the story here is to make sure you keep your SSN valid, and don't lose your social security card, even if you don't live in the US anymore, because you might need it in the future!
