not true, certainly not in my experience. The application is processed in India, not Thailand, so unless they have some special relationship with India they are only doing a service.
exactly, when we spoke to an agent after she said, they are looking for a reason to refuse, so give them so much information and proof there’s nothing they can use as an excuse for denial.
I applied myself the first time and met all the criteria requested. Application was refused, and I have used an agent the next three times without any issues. Basically you need to bombard them with a mountain of evidence and as already posted by others, one of the biggest items is a compelling reason for her to return to Thailand after the holiday. Our application is typically 2-300 pages of photos and messages etc
