Please, don't take me for a fool.
Of course there are guidelines, and proof MUST be offered before qualifying for payment.
How do you proved you stold a Social Security number 30 years ago --- and what if 5 other guys are claiming that it was they who stold it -- not you? If 6 people get together and claimed each one worked only 2 years for a stolen Social Security number that was used illegally 12 years by only one --- how do you prove they didn't? If someone claims that they stold your Social Security number and it was really them working some of that time when it never really was stolen and only you used it --- that can't be proven ---- especially if you are a dead guy when this happens -- you won't be there to deny it.
There was massive fraud in the 80's amnesty ---- because the undocumented really have no proof.
