I am an Italian citizens working in Shanghai.
I arrived to china with a 60days F visa double entry, then i ask for a 30 days extension at the entry-exit bureau in Shanghai. Now my visa expire on the 3th of October and i will be in Bangkok on 23 of september for vacation.
I would like to know if it is possible to ask for a new visa in Bangkok (also L visa should be ok because my intern ship ends around 15 of October) and how long does it takes?
If necessary i have all the documentation required for the F visa such as invitation letter from the company i'm working for.

Thanks for the help.

Best regards,
Filippo Iacconi
