Is it legal for my Italian uncle to transfer money from her credit card to my American bank account?

tl;dr - Is it legal for my American bank account to receive money from my Italian uncle's Italian credit card?

I'm an American stuck in Italy with bills to pay in America. Bills have ran my American bank account dry during my stay. My student loan services seem to only want to accept money from my checking account. Therefore I must find a way to send the money I have here to my account there.

How should I go about doing this LEGALLY?

Western Union says if my uncle creates an account, he can use his credit card to transfer money to my checking account in the states. Same goes for my fiancee.

My concern is whether or not this is legal.

I in no way want to be doing anything remotely suspicious or borderline legal. I try very hard to avoid any trouble from the authorities (IRS, FBI, and heaven forbid the DHS). But with all the anti-terror money laundering laws, I'm a bit scared.

Your advice is appreciated!

Thanks!
