I have to obtain a visa on arrival at BKK. The max stay allowed is 15 days. My return ticket from the US is for 20 days. However, I will be leaving to Cambodia for 3 days after 2 days in Bangkok, come back to BKK for 2 days, and then leave to Myanmar for 5 days, again coming back to Bangkok for the rest of the time. I have already purchased all my return tickets. Therefore, my continuous stay in Thailand would never be more than 15 days. Would I have problems with obtaining the VOA? Thanks!
