I'm pretty sure that any Visa/MC can be processed at Stripe, regardless of location. Country specific cards, like Diner's Club and others may require extra effort by the processing companies, and sometimes lead to higher costs. But can generally still be processed. Moral of the story is anyone anywhere can buy something from a US company using Stripe on their credit card.
