Hi, first, Thank you guys for your reply in my previous posts. I still have some questions about applying for tourist visa in Thailand.

How to entrust someone to apply for the visa on my behalf? If I ask a friend to go to Bangkok and apply for the visa on my behalf, what kind of documents I should give to this friend besides my passport? Do I need to write a letter saying that this guy is representing me to apply for the visa etc., things like this?

Thank you so much in advance.
