Hi folks. I would like to share that the Thai Embassy in Penang(Malaysia) no longer issue the 90 Days Non-O Visa for Dependant based on spouse's Non-O Retirement Visa. My wife got her 1 Year Retirement Visa in Chiang Mai recently.
Please take note of the new regulation.
Here is a reply from <thaiconsulate.pen@gmail.com> that I received yesterday morning. You may further verify with them if you wish.
