HEADS UP FOR ANYONE ELSE CONSIDERING THIS:
If you are going to receive funds with PayPal and they are going to exceed the 'occasional sale' guidelines (which some people interpret to mean the same guidelines at the rule for sending an IRS 1099 form which is First establish your business presence in the US, that means creating an LLC, getting an EIN [1] and establishing a relationship with a US based bank.
If you get hung up on those steps, don't start taking money with PayPal because their zealous anti-fraud/laundering/drug program fires on a hair trigger. It didn't help that the OP is a student from Venezuela which is not one of America's trading partners.
I expect you will lose most of this money in legal fees. However, if the business is durable, and you manage to establish your LLC (that lawyer you got can help with that) then you will make it back and PayPal will back down. As long as the money trail can be tracked and everyone in the path reports it to the Federal Government so that they are satisfied it isn't part of a laundering scheme[2], or if it was they can catch the folks involved, you will be ok.

[2] This is how the laundering scheme would work. Some criminal enterprise hires a bunch of third parties to buy your 'widget' for an inflated price, say $10,000 per copy. You sell the 20 copies, get the $200,000, now you go to a coffee shop owned by the criminal enterprise and buy a Double Vente Latte for $180,000 made out of hand picked coffee beans. The crook now has $180,000 of "legitimate" income from his coffee shop, you have $20,000 in "profits" on your amazing Javascript widget, and 20 drug dealers have a bit of software they just delete from their hard drive (if they down loaded it at all). Everybody "wins." So the US Government wants to be able to subpoena your customer list to track the money from the drug dealers to you and then back to the crooks. Paypal helps with that. If you make it hard for them to do that, they keep you money.
