Has anyone left the country within the first year on an O-X visa that can advise on their experience with insurance? Do you need to show proof of coverage for the next 12 months when you fly back in?
I am intending to apply for the O-X soon but will be making trips out of the country to do some travel occasionally, most likely every 6 months or so
TLDR : Answer Summary
The general consensus among commenters is that once you have shown proof of insurance upon your initial entry with an O-X visa, you do not need to provide insurance documentation for subsequent re-entries during your visa's validity period. It appears that only the first entry requires proof of insurance for a full year; thereafter, you are not asked to show it again when you re-enter the country.
