We're traveling from the US to Thailand next month, and plan to partake of the VISA on arrival for the new 45-day period. Do we need to have VISA/Passport style photographs available when we arrive, or when we apply later for the 30-day extension? If so, what size exactly do they need to be? Matte or glossy? I had photos prepared to submit for a tourist VISA but we've opted to not go this route. I want to have the photos pre-printed so we're ready to go if we need them.
