If you follow the rules and get passoort verification and address info from the embassy as your supposed to no need pay anything.
That some foreigners like to pay "money" to ignore rules and they say thailand is corrupt is funny. They themselves are corrupt for not following the rules ;-)
Find the rules and follow them and you shouldn't need to pay any extra. Especially if you got writing mwithon the rules.
I'm not aware of any visa that allows you stay in bali 60+ days?
Generally, must westerners can enter visa exempt 30 days. So it's cheaper often to switch country every month than do visas. At least less paperwork etc.
Well, yes if you fail you can take private lessons to catch up to be able to continue, typically.
Sadly enough I need to start over because I studied Thai 2 months but then we had locked down and I didn't use it for a year cuz it was no but it's high I could speak to so I forgot most of it.
Sometimes if a web browser reloads a web page the booking site will happily book the rooms again and again and again!
This is just programmer malfunction I would say because they should have a code requiring a new session to be started to book another room but a lot of programmers are stupid. This happened to me on Expedia they booked the same room twice because the first page didn't load I didn't reload because it was nothing in my browser and then oh I have a room good only I had two rooms and I only saw it later on the charge. I did the mistake of letting them give credit which only lost it for a year I should have asked the money back and I should have forced the bank to give it to me.
