Hello guys. I'm coming to Bangkok in May. Since my country is in the list of countries that have the exemption from the visa, i won't need a visa to stay in Thailand for up to 30 days. However, my flight going back home is on the 31st day; that is 9am on the 31st day (i booked as I thought the days for visa are calculated by 24 hours).
I enter Thailand at around 7:00pm to 7:30 pm.
Can i get an extension for the 9 hours I'll stay more in Thailand before my flight?
Will I be allowed to enter Thailand?
P.s: getting a visa before traveling means sending my documents to the embassy in South Africa by courier. Also, changing my return date is costly (it will be better to pay for an extension).
Thanks guys.
