Why? There was nothing in the article to tell whether or not his other Hispanic employees were illegal. It also did not state how good Hernandez forged ID was. Was it only good enough to "fool" an willing employer just looking to fill out an I-9, or did the police have to go back to ICE and track down the ID numbers to see that they were being used by multiple people at once?
Since I've never had to deal with it, is there any way to call the government and verify a green card?
I couldn't find a transcript but this morning on Fox & Friends they discussed a Mexican family who runs a business of creating counterfit documents, including ss cards, green cards, etc. If I recall correctly, it was said that this business operates in 50 states and the counterfit work is so professionally done that only an expert can tell the difference.
