From the FAQ's (http://ycombinator.com/faq.html http://ycombinator.com/faq.html) Do we have to start a company in the US for you to invest in us? Yes, but that's usually not a problem. It's easy for foreign nationals to start US companies (much easier than remaining here physically), and investors and acquirers prefer them. Do we have to be US citizens? No, as long as you can get here for at least three months. We've funded many startups founded by non-citizens. Can you get us visas? No, sorry, we don't do that. You'll have to figure out visas for yourself. If you know people from previous YC-funded companies who came from outside the US, we suggest you ask them for advice. They understand the options better than we do.
