WTF are you dreaming up??? The two land border crossings per calendar year only apply to visa-exempt entries!! HE's got a multi entry tourist visa, he can enter across a land border as many times as he wants during the 6 month validity of his visa.
you can get utmost 2 years out of an ED visa, and later when you try to enter the country, they refuse. An ED visa is , like somebody else already wrote, a "trap"
the only visa that allows one to keep money in the home bank, is the 365-days multi entry Non-Imm-O/A visa, as Brandon Thurkettle has already correctly posted.
This is quite another topic, you are talking about the "visa validity". This is only valid for multi-entry visa. The right to enter remains valid for a certain period, but you still receive a "stay permit" upon EACH entry. And please note, most Thai embassies do not issue 365-days multi entry Non-Imm-O retirement visa any more. They only issue the 90-days single entry category
then your friend was just lucky, the Immigration officers had a fine day, and thought "let's give both of these guys an extension, so they don't need to come back" . . . . .and by the way: There is NOTHING such as a 30-days visa-on-arrival. It is called visa-exempt entry and you receive a "stay permit" of 30 days
When you apply for a visa in the E-Visa system, your application will be forwarded to the Royal Thai Embassy in London, U.K. And THEY decide if you will get issued a visa or not. Thus, if I say that the Thai embassy in London is "doing" or better, "issuing" your visa, I am totally correct
