Is WISE transfer considered an acceptable international transfer for a one-year marriage extension in Thailand?

Yes, state ‘for long term stay in Thailand’

Many immigration offices (specifically hua hin) will require credit advice statements for foreign deposits if required. One for each. They don't recognize what's printed on the statement. They want the detail... Just my experience 2 months ago....

In my case, Wise to Bangkok bank show as international transfer but SCB and Kbank are not.

Bangkok bank take time to arrive money but SCB and Kbank are instant.

Wise partner with Kasikorn bank and I can say that Kasikorn is a very good bank to have an account with

The 1 year extension does not require an international transfer of funds.

Reason for transfer in Wise must be " funds for long term stay in Thailand". It shows as international transfer.

2 things:

1) Extensions do not require proof of international transfer unless you are doing monthly transfers.

2) In order to get Wise to attempt to show as an international transfer, you must select the correct reason for the transfer. It says something like "funds for long-term stay." Choosing this is not a guarantee that it will show as international, but they will attempt to get it to do so.

But to summarize, you don't need to worry about it in your case. Both the 1-year extension for marriage and retirement are not required to show as international. It's only the conversion from tourist to non-O retirement that requires this for lump sum.
