Coupled with a photo ID (such as a state issued driver's license or ID, not a fake Consular Card), it doesn't take very long to find out if someone is here legally or not. Legal residents of foreign extraction also have green cards.
That's what I keep thinking, you CAN find out. If someone has very good fake documents, it may not be so easy, but you would also think that when someone uses a fake SS card for any length of time, the SS office should catch on. That seems like a nobrainer as well.
That's why I believe the people in charge do not CARE!
