, that's not quite true, :/ IF you are getting a 90 day Non-O visa inside of thailand from an immigration office you DO show you have 800K banked BUT there is no seasoning on it.
I had an aussie who came here on a visa exempt 30 day stamp, he transferred in 800K baht, we went to the immigration office the next day and applied for the 90 day Non-O visa without a problem.
Now, most thai consulates in the area want to see 800K banked (or the consulate notary letter of 65K baht income) to issue you a 90 day single entry Non-O visa based on being over 50 (retirement)
