I am an American citizen currently in the Czech Republic. I plan on leaving the CR in almost a week for China. I have some questions about getting a Chinese visa.

1. Is the application form filled out at the Chinese embassy or do I need to download and print it before I get there?
2. I understand that it usually takes 5 business days to receive the visa. If I am an American citizen temporarily in CR, will it take longer? (In other words, does the application have to be sent back to the U.S. first?)
3. If I don't have a bank account in the Czech Republic, how can I pay for the visa?
4. Do I need a flight ticket to China before I can receive a visa?
5. Do I need to show where I plan on staying in China?

Thank you
