when you enter Thailand on a 30-day tourist visa, the immigration officers usually want to see a return or onward ticket with a departure date. But for the 30-day extension, you don’t really need to show an exact departure date-just make sure you apply before your first 30 days are up.
You don’t need to worry about having your departure details 5-6 months in advance for the new Thailand Digital Arrival Card (TDAC). The system only lets you register up to 3 days before your arrival, so you can fill in the departure info closer to your actual travel date. Just keep your travel and accommodation details handy for when you register within that 3-day window before you fly in. Departure info isn’t required way ahead of time, so no stress on that front! Just make sure to complete the TDAC online before you arrive to avoid any hassle at immigration
In cases where your passport is torn, separated, patched, damaged, or burned..., you must immediately notify your nearest consulate for a final decision.
