What should I do about transferring 800k baht using Wise for my retirement visa extension in Thailand?

Avoid Bangkok Bank if possible.

No for your extension it does no matter where it comes from but for extension normally u need 400k for the last 12monrh on account and 800k 2 month in advance and 3 month after..

!?!

Pour moi le problème avec mon visa non immigrants 0 valable 3 mois c'est les banques pour le moment a Bangkok ne veulent pas ouvrir de compte en banque, visa touriste?quelqu'un a réussi a ouvrir un compte en banque pour extension de un an pour placer les 8.00.000 bath au mois août ou septembre?

When I did my transfer it was internal, they couldn't care less.

I never had issues with Wise transfers but recently not being marked as foreign transfers by one of the banks. I moved to Kasikorn now but i am sure we can always prove the transfer by providing the Wise statement.

Do you have a Thai bank account already? That will be your biggest headache by far.

Use swift

It's not a problem. Retirement EXTENSION using 800k is not required to be an international transfer. It's only when applying to convert from tourist to non-O inside of Thailand that has this requirements.

The people that are having problems are the ones using monthly transfers to qualify as proof of monthly income for their extensions.

If you want your transfer to show as international regardless, select the proper reason for the transfer and Wise will attempt to get it to show as an international transfer. Highly suggest getting a Kasikorn bank account for better odds based on recent reports.

But even if it doesn't show as international, the transfer into your bank account will show which Thai bank it came from. You go to that bank with your Wise receipt and ask them for a credit advice which will show that the money was international.
