Work permit with tourist visa

[rocks860]

Hi there,
My sister lives with me, and she has a green card. She has one year here in the US. A guy is dating her, but he is does not have a green card. He got here with a tourist visa, and then he said he applied for a work permit and got accepted. Now he has a job.
Is his story legit? Is there a way to proof that?
The thing is, if they get married, and his story is all a lie then chances are he might get deported and banned for 10 years or something.

Also, he said that he is renewing the work permit and he got a letter 3 days ago saying his application is ok.

Any tips will be appreciated

Thank you

If someone on here tells you that it's not possible there is no way for you to prove it so i'm not sure how this helps.

If he came on a visitors visa he wouldn't be able to apply for a work visa and THEN get a job.
A visitor in the US is not allowed to work. So either way it's not looking good.
