I dont think there is anything written in official rules. However, it may come down to an individual officer not looking very positively at someone, who is trying to enter the country, having exited just 5 minutes ago.

I have had AIS and True. So I cannot really speak about DTAC... But between these two AIS seems to be more reliable when in remote areas. In big cities / highly populated areas both seem to work equally well

I have a decent AIS LAN in my house but I still have a large volume mobile data package on standby in case the WiFi does not always work. And I have had to use it a couple of times. This is Thailand. Power cuts and network cuts happen... and not too rarely

Sam Lewis Not easy, if you just want to get the 5% for the money sitting in your account. There are plenty of low risk investment opportunities that can give you much more than 5% per year

Or you can always look for a visa run company that will take you to a 1 day trip in Malaysia...

Charlie Gould 10 minutes for 90 day report, yes. But for the yearly extension you will be done in 10 minutes only in your dreams. But, as I said, to each their own. When I will be in my 50s (which looking in the passport is unfortunately not that far anymore) I would much rather take some course and a trip every 6 months than queue up with a stack of papers in immigration every year, and keep 400 k virtually locked up forever, and another 400K locked up for half a year every year.

Joanne Ramsden If you do it yourself, the visa fee is just about 12K THB. Plus the money you pay for a course... And no need to keep the money locked up every year like for the retirement visa. No need to file new documents every year. The only requirement is to take a trip every 6 months. And to me it feels much more pleasant than sitting in a queue at an immigration office. But I guess people are different...

8 years ago when I got my ED-visa, I asked the school to contact the bank and work things out for me. Before doing that I went to at least 4 or 5 branches, who all (more or less politely) sent me on my way. Ask your school, they probably have some contacts in some bank.

จอน สู้สู้ First reasonable reply 🙂

Graham Seal And then 5 months in the following year, and a year after that and a year after that and....
