What happens if you intend to have an extended holiday and you will be staying with your girlfriend at her rented condo? Does she have to pay 2-3 months of rent in advance just to satisfy this ridiculous requirement?
It's beyond ridiculous and in the next breath they are crying out for tourists. There's a reason the numbers are down. Who wants to go on holiday and jump through all these hoops.
There are a few on here who like to be judgemental and don't take people's circumstances into account, just because "I'm alright Jack". It is possible as Thailand is flexible, just be aware that people get transferred and agreements can change. Do you research on the company.
