Don't take this the wrong way, but have you had experience with CW? I said I have transferred the 840000 in this year, x amount each month. Not 65000 regularly. But the total for the year is over 1300000. My thai wife was with me and we asked the lady supervisor "aren't you able to have the 800000 as money in bank for 12 months (over 400000) plus transfers in totalling over 800000." She wouldn't answer and deflected back to the 65000 each month regularly.
I was originally trying for marriage to the extension. What a nightmare that was. We were married in australia. CW wanted it legalized at thai consular services. Thai consular services wanted it notarized by Australian embassy and translated to thai. There was some mention about KOR 22 but by that stage my head was spinning so I dumped that idea.
Oh, here's another good CW story, my visa started 23 sept. I had 800000 in the bank and was allowed to take money out after 3 months but balance had to stay above 400K as I'm sure you know. On 23 Dec, I withdrew 30000. When I went to CW yesterday, they say I withdrew the money 2 days early (notice I said they, not just 1 person, a few of them). Wot????? I patiently explained (i call it logic) that my 12 month visa expires on 22nd, that means 12 months finishes on 22nd. So if 12 months finishes on 22nd, 3 months finishes on 22nd. Means I can withdraw on 23rd, which is what I did. After about 1 hour of waiting while high level discussions took place, they eventually agreed. My head was ready to explode and my thai wife was nearly in tears, lots of other visa staff came to tell her not to worry. Can you understand why I might be interested in using a visa agent for this extension. Next extension will be 65,000 monthly, or if this is as easy as i read, i might stick to an agent. CW can be a nightmare or it can be easy. I hear more nightmare stories than good ones.
