@Vladimir *******
that is exactly what I have been planning to do so that I would be on the correct visa every time I would be entering Thailand for the next 12 months. I am just worried that there would be an issue with me not using it often, as I would only be using the multiple entry visa to enter Thailand from Laos next month, enter at Bangkok in December and enter at Bangkok in May/June. My understanding is that it would be the correct visa for my circumstances but just worried because I’ll be outside Thailand for the majority of the time that the visa will be valid for. If I was sure that wouldn’t be an issue with immigration, then I would prefer to get the non-immigrant O visa when I have the opportunity to go to Savannakhet to get it next month, rather than entering on visa exemptions each time.
