How do I use my DTV visa upon arrival in Thailand?

The DTV visa, received via email, serves as your entry document to Thailand. Upon arrival, you should present either a printed version or digital copy of the visa email to immigration officials who will stamp it into your passport for a duration of 180 days. It's advisable to keep multiple copies, as you may need to show it to airlines or immigration multiple times. While some individuals have successfully used their phones to display the visa, having a printed copy for security reasons is recommended. For additional verification, visiting a consulate or embassy to have the visa printed in your passport might facilitate processes like opening a bank account.
