Good morning, I am (UK55) moving to Cambodia in November. I am travelling to Cambodia tomorrow for a few days, if I return without a reentry permit will I just get 45 days on arrival, and my O visa (based on "retirement") be cancelled?

If I don't plan on returning before my O-visa expires (Dec) is there any advantage to be gained by getting the reentry permit?

Hello, My retirement visa is coming due on the first of June and I am thinking about relocating to Cambodia. I just don't know if it is in my best interest to leave Thailand before the date or obtain a new visa with a re entry in case I decide to return to Thailand? what advice would you give? TIA.
