So, it's basically a pain to travel.
If I want to take a trip out of the country, I need to spend half a day getting a re-entry permit and transferring my visa from my current passport to my next one. I really should do it anyway, in case I need to travel for an emergency.
If I want to visit China, I have to take 2 mornings and get a visa, once I've bought a plane ticket. I also need a letter from a Chinese tour agency. I'm not sure what to do if I'm not going on a tour.
