Anonymous participant Where are you applying? Anywhere but Laos should be fine to do that but best to submit 6 months worth of statements (some require that) but it doesn't mean you have to hold 500,000 for the entire 6 months.
With so few international flights and the apparent scrutiny being applied, not sure why anyone is flying into Chiang Mai. Just fly to Bangkok and if you're living in or wanting to visit Chiang Mai and need to get there quickly, book a separate domestic flight. Besides, nearly all international fares into CNX are way more expensive than flights to Bangkok. I remember comparing EVA Air to Taiwan from CNX, not only do you only have one narrowbody flight a day, unlike the 3-5 daily EVA flights out of BKK but fares were TWICE the price of ex BKK fares.
It's similar, but generally an employment certificate is shorter and confirms ongoing employment. Can be 1-2 pages; whereas a contract can be rather lengthy.
Documents need to be translated into Thai or English at MOST consulates around the world, whether an applicant likes it or not. The exception being a few European consulates, which take certain documents issued in the local language.
Pretty unlikely anyone would come to Thailand without knowledge of at least English and preferably Thai as well. They'd be completely unable to communicate with anyone and Thais would be scratching their heads at how can a foreigner not speak English?
