Many places I go to in Thailand don’t accept credit cards and debit cards. It’s cash or scan using your Thai bank app on your phone. Based on that, this card has no advantage for me. Also, if I go to a place that accepts credit cards, I’m using my own card so I can get the cash back or miles.
I did this in December 2023. US passport. Applied for a tourist e-visa from the Seoul Thai Embassy. Left Korea 5 days later and arrived at Suvarnabhumi to get the 30 day visa exemption. 2 weeks after arriving in Thailand, my visa was approved. At the end of my 30 days I did a border run to Poi Pet. Visited Cambodia for 20 minutes and returned to active my e-visa.
They had to have known I boarded the flight that I showed for the visa.
Graeme, I can’t advise you on what steps to take, but after many years of learning about Thai culture, I can recommend try to not express emotions when working with the immigration system. It’s painful because often times what they say makes no sense to our western culture and thinking. My wife explains it after we get home, then I begrudgingly understand. Good luck.
If it is your plan to visit Thailand, you will have no problem. If you plan to live in Thailand using tourist visas and visa exemption on arrival, you will experience difficulties.
