Wow, the sheer quantity of unhelpful advice in this thread is simply mind boggling. Hey, let's all hate paypal because they "steal" people's money. Ignoring the seriously thorny legal bramble that the OP has run headlong into with nary a concern. There is a bounteous variety of comments of the form "Paypal sux! {Use X instead!}" Where X may be stripe, or wepay, or whatever. Ignoring the fact that stripe wouldn't help in this case (it's US only), if you go read the terms of service of stripe or wepay you'll find exactly the same things there as are at issue here. You'll need an SSN or EID or tax ID with stripe too, just as you would with a WePay business account. There's a reason for that, and it has to do with the law.

There are maybe only half a dozen reasonable, substantially helpful, and actionable replies in this whole thread (which would put it at maybe a 4% SNR), almost all the rest is useless. If this is what HN is going to be, I don't want it.

As for my advice, it's simple. Go talk to a lawyer as soon as possible, you have a lot of issues that need sorting and a good lawyer is absolutely necessary to get through those issues, and they'll help to put you on the right footing to deal with paypal. It sucks that you have been acting in good faith and doing good work and have gotten tangled in the mess that is the many layers of laws, regulations, and corporate policies that make up our modern immigration, taxation, and financial systems. You have my sympathies for that and I wish you the best of luck, hopefully you'll be able to keep the proceeds of your excellent work without any serious negative repercussions.
