@Tod ********

thx for the comment, last year same time didn't mention it, and a friend did same extension a few months back and wasn't asked as well. Got away as my kid is not yet 3yo and is just in pre Kindergarten, anyway good to know for next year 👍

Got the letter without any problem 👍

Thanks guys!

if that includes the official fees and all expenses of the agent it's not too bad, you will also need the re-entry if you travel a lot, 3,800 THB for multiple if I remember correctly

I did this 3 years ago from non-b to non-o based on marriage, although not BOI my company was under the one stop service at Charmchuri Square. I actually used the agent/lawyer that my company was using to do the process and paid them personally to handle the switch. You can do it yourself but you will spend quite a bit of time. if you have more important things to do, any law firm dealing with visas will be able to handle it for you, just have to find one that doesn't charge too much 😁
