I am in the process of filling out forms for O-A Visa I downloaded from Thai Embassy in Ottawa ,Canada. Couple of Questions I'm not to sure about. - Proposed address of stay in Thailand . I am assuming that would be the Hotel or Guest house I will be going to when I arrive. -Reference Person in Thailand . Not sure on that one -Countries for which passport is valid. Not sure What that means either. Hoping someone is familiar with these forms Thank-you
