If your employment is secure, is there any benefit of transferring him to an Ed visa, rather than remaining as a dependent piggy-backing on your work extension?
Thanks. Then presumably at passport control at the airport in Bangkok we just show the Extension stamp and Re-entry permit in the cancelled passport? Then get them transferred into the new passport later?
That's how it works for many parents of non-Thai kids. Enter on visa exempt and then just stay. Overstay fines and bans are not applied. I prefer to do it properly; but I know many parents who have been told it's ok by Thai Immigration.
Exactly. It's being "jobsworth" in the extreme to insist very young kids, who are entitled to a visa exempt entry, buy an onward ticket they couldn't possibly use!
How old are your kids? My 3year old is piggy-backing on my Extension but there have been times when I've been tempted to let him enter visa exempt and just overstay. Not sure I'll do that now, in light of your experience!
