You're still off the mark. He's talking about another extension by himself to an extension made by an agent.
He stated he was putting 64k in the bank monthly. That's wrong and won't be accepted.
He also wants to apply for a new extension. It's doubtful that he had the 800k in the account for three months after receiving his current extension. That's another fail.
So in no aspect has he got his finances correct to do what he wants to do.
And if you think 800k four months before an extension is a safety margin to the two months required by immigration, then state it.
The reason why so many ask almost daily the same question is that over 50% of the replies are irrelevant, inaccurate or conflicting.
Probably it's even worse, because I've now blocked several hundred posters who post utter drivel, possibly from Soi Buakhao during the afternoon half price beer session.
However, they are vastly outnumbered by the silent customers who have no problems at all.
WISE now has in excess of 15 million customers, roughly growing at 20% a year. It's inevitable that some transfers will have issues.
SWIFT transfers are more difficult to set up and track.
WISE is easy and the tracking is provided automatically with an estimated time to arrive.
If a SWIFT transfer goes astray, you are left dealing with the banks directly. WISE takes care of all that hassle.
You can also thank WISE and similar companies for breaking the banking monopoly and bringing down transaction prices and narrowing exchange rate spreads.
With WISE you can also send directly to various wallets such as in the Philippines, Indonesia and Malaysia, an extremely useful feature.
