You need to check what the requirements are to leave PH as your government have specific requirements for citizens travelling to Thailand. I suggest to join PH Thai group on FB
Most offices will not accept a Google map but insist on the wife hand drawing one. Last year I supplied 4 photos of us, 2 inside and 2 outside. This year they want 8. You only need 2 months bank statements. The 400k is supposed to stay in the bank during 'under consideration' but mine never is as it goes back on deposit earning some interest until the next time.
You have a Multi Entry Tourist Visa METV It is valid for 6 months but you can get nearly 9 months if you time the last entry correctly. Every time you enter Thailand within the 6 months validity you will get 60 days permission to stay which can be extended by a further 30 days at a cost of 1900 baht. Others have already stated when the extension can be applied for. At the end of the 90 days, you have to leave Thailand but can immediately return for another 60 days and so on. The 6 month validity started the day you arrived in Thailand.
So have you got a free 60-day visa-exempt entry or a 60-day tourist(TR) Visa? I suspect it is the former so please stop calling it a visa as this only confuses ppl.
Common sense is unusual in Thailand 😃 I was told they want a translation as that will be how your name appears on the pink card and they needed to record my parent's name in Thai for some unexplained reason
