I've arrived last week in Thailand and entered with a visa exempt. Two days later, I have received the confirmation and approval for my DTV visa, which was under processing prior to that. I've mentioned this situation to the IM officers at the airport, and they said it's no problem, I just need to wait for the confirmation, and once it's done have the stamp exchanged at the local IM office. I went to Huahin office and see if I can have the stamp changed, but they said I have to leave and re-enter the country. Please let me know your input on this. Thanks!
TLDR : Answer Summary
The user entered Thailand on a visa exemption and received approval for a DTV visa. They were told by immigration officers that they could exchange their entry stamp once confirmed. However, when attempting to do so, the local immigration office stated that the user must leave the country and return to activate the DTV visa. Community responses confirmed that it is necessary to leave Thailand and re-enter to activate the DTV visa, with some suggesting border runs or trips to nearby countries.
