Hi Everyone,
I wanted to update you on my original question regarding changing visa type. I was successful in doing so in April, almost 6 months before my current NON-O Retirement visa expired. I had to write a document that stated why I needed to change early and stated that I was starting a job in Thailand the same month. After that they proceeded to accept the application and it was approved.
After that I applied for work permit using form 1 rather than form 3 for work permit issuance and it was approved about 4 days later.
In the end the requirement was the reason why documented and signed.
The process went well and I am now working in Thailand again.
Thank you to everyone that replied to my question and contributed to the process.
Regards, canadian
