, depending on your nationality you might be able to get your embassy here to issue an "income from abroad notary letter (the US, UK and Australian embassies do NOT issue it) but some other consulates will.
you wouldn't need to bank money here if your consulate will provide that notary letter stating you get a minimum of 65K baht a month in income from your country.
