I'm traveling from the NYC to Tokyo. I have a connecting flight in Beijing. Do you need a visa?

If your transfer time is within 24h and u don't wanna get out of the airport, no visa is needed. If you will transfer within 72h, you are qualified for 72h free-visa policy, you can put forward your request to your airline in advance so that you can be issued a stay permit upon landing. With the stay permit, you will be allowed to get out of the airport to a short visit. If your transfer duration is longer, a visa is needed!
