3 years ago, I was in a similar situation. I had 5.5 months left on my passport. I needed to do a boarder bounce before applying for a new passport in bangkok. I flew to Hong Kong (they only red 1 month left) for the day.
Before I left bangkok, I double checked with the check in counter and they checked with immigration. I had no issues coming back to thailand.
work permit valid until 8 of January next year. I'm just confused about my lawyers warning. But I think that it's lost in translation. Shim can get an education visa and Stef dependant but 500 000 in bank for five months for that one
The company I work for writes in English and so far my husband has had no problem getting his dependent multiple entry non o visa from both penang, kota bahru and London.
