I'd like to know if it is possible to get a tourist visa (10 days at most) for China in Phnom Penh?

Yes, I think you can aply there. It takes four working days and you you should submit your passport, completed application form, a recent passport photo, air tickets and hotel reservations. You can go to Chinese embassy form 08:30 to 11:30 from Monday to Friday.

hey
thanks for your fast reply. i have another question. i read something about a socalled rush type. if i would go there friday morning can i pick it up in the afternoon the same day? my flight is saturday morning.. so i definitely need it on friday.
or is it too risky?

Stephan, there is a rush service. However, you need to ask permission from the officer. Without his approval, you can't use rush service. It costs extra 30 USD. Please submit your application before 11:30 if you plan to use rush service.
