Yes you're right it's a Non O + 1 Year. It cost 25K for the Visa and 3K for the Bangkok Bank account. They took me to immigration, escorted me to the front of the line, took my picture and I was out of there in 1 minute. From beginning to end everything took about 2-3 hours. Manareet said once my 15 months runs out I can renew for 12 months for 12.5K. If I do 27 months here I estimate the cost comes down to 1.5K(40K Total)a month.
