Hello

Is it possible to change my Visa inside Thailand, when I have a Non-O (marriage)?

and which paper I need to show them?

Is it also possible to show them my Austrian bank account with the amount of Euros equal or higher of 800 000 Baht or Original document of my monthly income in Austria?

Thanks a lot for your help

Have just set up a company 2 months ago. Everthing in place just missing a few requirements for my visa change due to it being a new company.

Am currently on a tourist visa and just found out i can change my visa to a non imm b at my local immigration office in Ranong without going to Penang. Any experiences with this? More paper work..harder to do?
