Hi

For how long should I book my stay in Vientiane, to apply for a tourist visa back to Thailand?

Hi Guys just got my travel exemption approved and i am applying for my OA visa

the application form says i need to complete a Personal Data Form which can be downloaded from the website but i cannot find it on the website,also they are asking for a local Guarantor,what is their expectations of a local guarantor and finally the contact details of guarantor in thailand (if applicable) so i just leave that one? many thanks with any help you can give me
