Update for me, I went into a branch in Bangkok (home branch is in Koh Samui). The lady called the Samui branch and was told they will unlock it tomorrow.
Be sure to consider that if you are no longer a tax resident in your country you could become a tax resident in another. Sometimes your country is a better choice when tax treaties exist.
yes, I had G M on my canadian license. They didnt even look at my IDP. I just went in with Fat Boys and they helped. It was a walk in the park. I also needed the residence letter.
