I have to disagree.... I also have a non-O and I did transfer the stamp when I got my new passport.
The sticker can’t (given by the Thai embassy) can’t be transferred.... but the 3 months (not an extension) stamp I had entering at the airport has been transferred in my new passport.
I was leaving... I went to CW bangkok... I asked and they told me I had to transfer the stamp even if I am leaving...
Now maybe they just wanted to make me lose my time... but it is transferable.
So I don’t really know if you “have to” but it is doable.
yeah... we are still trying to figure it out... most of the other kids are interested in hospitality or management... so I heard it was quite easy for them to find something...
My son is much more into sciences ... biology... he has no idea yet how he is going to do that.
