Thanks, are you sure as I will need to do check in again for the connecting flight? "Even though the traveler has a connecting flight within 24 hours of arriving in India, they may be required to leave the airport Transit Area for one reason or another. For example, it may be necessary to clear immigration to recheck luggage for the connecting flight, or because the travel wishes to stay in a hotel outside the transit area. "
In my country that is almost impossible bcs of the let's just call it old fashion bureaucracy; I tried that and even though I showed proof of income and all, I was asked to show 4 plane tickets in-out Thailand. When I said I will provide also those I was told that even so I might be denied unless I show I have a boat cruise that shows i am going in-out Thailand :D. So my only options would be to get it from the US, Australia or Canada. If you know other countries that grant METV for non-residents that would be really helpful!
On my side I stayed around 150 days with my first 2 SETVs this year and had no problems at CM airport when entering the 3rd time. No questions and was not asked to show the 20k baht. Although I was prepared for this because of the remark I have on my last visa. BTW, thank you all for your answers!
