I live with this woman who is married to a friend for the permanent visa and I can't do anything about it unless she reports him

If Immigration hs told you there is nothing you can do - and you have reported the fraud - then there is nothing you can do.

SHE needs to do something.

Thank you

And if she hasn't bothered, it might be because he paid her a lot of money to marry him, and he will get her in trouble if she gets him in trouble, so be careful what you do. And be careful what you believe. Meddling can bite you.
