"If they mean to include illegal workers who stole an American's Social Security number then I say hell no!!"
The GAO calls the illegals "unarthorized" workers. Yes,l they are covered under this agreement.
Try this government site second paragraph:

As I said, I strongly disagree with giving Social Security benefits to illegals who used stolen Social Security numbers.
