You also need it if you decide to get a Yellow House Book and a Pink ID card through your local Amphur office
FYI…you can use the 13 digit ID number to get a DL which is convenient since you won’t have it tagged to your passport and new renewal number…also for bank acct and SIM cards along with hotel registration
After you get the visa then you can do the ฿65k but remember it has to be 12 consecutive months for the ฿65k
Which usually takes until year 3 due to overlapping months from when it’s renewed to when you start the ฿65k deposits…the deposits have to show correct verbiage as well for them to be accepted by the I/O
So most people put the ฿800k in a bank acct and forget it exists until the yearly renewal date
One of the reasons they want to see the ฿500k in a regular bank acct is because the immigration/govt wants to make sure you can support yourself for the duration of the contract
