Hi, I'm Korean and living in the Philippines. I have a plan to go to Beijing with my daughter on March 25. My concerns are :

1. Can I apply for maximum stay of 90 days on a single entry tourist visa? Some people say that only 30 DAYS is allowed for L visa. I don't want to extend my visa in China.

2. One of requirements is a copy of round trip plane ticket. If only 30 DAYS STAY is allowed (so I have to extend my visa in China), should my return flight ticket be within one month? It means, when I extend my visa in China, I have to change my flight schedule also, Right?

3. Hotel reservation or Invitation letter?
Do you want Hotel Reservation for the period I stay in China or just first few days are okay? If I can get invitation letter from my Chinese friend in Beijing, can I ask him to send me a letter which includes general informations and a copy of his ID through e-mail?

Please help me...
