Respected Sir/Madam,
I am an American citizen studying in Jilin City,Jilin Province, China.
I require a thai tourist visa to visit my fiancee in Chiangmai for 45 days.
I know that i can get a free visa on arrival but that is only for 30 days and i want to stay in thailand for 45 days.
My question is that can i extend my free visa on arrival which is of 30 days while in chiangmai?
if it is possible please let me know about the charges and conditions.

If the extension is not possible ,may i know if there is any way i can apply for the tourist visa via mail from Jilin city?
i cannot go to beijing for the visa at the moment so i want to apply for the visa by mail or post while in jilin.
If this way is possible can you please inform me about the charges and conditions?

I have an American passport expiring after 9 years so i have no problem regarding that matter,and i have suffecient funds to support my
self during my stay.

i will be eager for your response.
Adam Ak
