Yessir and you would need to be an expert to tell the difference for the higher priced ones. The most common scam is they work under a relatives social security who got one during amnesty. So that social security number is working and when they get to the proper age someone who is living in Mexico “retires” and gets a pension from the US taxpayer in the form of social security. This is actually going on right now as many who received amnesty are reaching retirement.
