What you should have done (and this is still a legal uncertainty) is have the funds tied to a Venezuelan bank account, your Venezuelan personal and tax identification. It's a little late for that, however.
Best of luck retrieving your funds. I wouldn't be surprised if you got PayPal to release them (they are not themselves a government, so just require enough information to cover their own ass). But expect to be asked some very serious questions by USCIS. For that reason you don't want a regular lawyer, you main issue here will be trying to convince the US you weren't breaking your visa terms.
You need an immigration lawyer.
