Hi,
I am a U.S. citizen touring Asia just for the summer vacation. I am currently in South Korea, but would like to travel to China, then Vietnam, back to China, then back to Seoul. I plan on being in China and Vietnam for about a month total. Is it possible to get a visa at Seoul? I don't have an Alien Registration Card. Is my American passport and application with photo enough? What else do I need? How long is the processing time? Also, which visa should I get? Some people have said you are located near a bookstore? or are the directions on this website more accurate? Thank you!
