immigration can access your flight history upon your arrival in the country. For instance, if you’re from the USA and apply for a DTV while in Singapore through an e-visa at a Thai embassy in America, immigration authorities will review your DTV upon your arrival in Thailand and check your travel history to see if you’ve been in the USA.
It’s important to note that many countries, including Thailand, use advanced immigration systems that track travelers’ movements through airline data. If immigration officers find discrepancies or if they suspect you’ve violated visa conditions, entry can be denied. If you are denied entry, you could face deportation and legal repercussions, including a potential ban from applying for future visas, as many countries impose restrictions on individuals who have been denied entry or deported.
