My multi entry o-a visa runs out on December 14. This is the first time I have reentered with this visa. If I extend my health insurance till late July will my visa be extended to july at immigration Bangkok. I intend returning November 30.
TLDR : Answer Summary
A multi-entry O-A visa allows for multiple entries into Thailand as long as the visa is valid. If one reenters Thailand before the expiration date of their O-A visa, they can be stamped in for the duration specified by their health insurance, provided the insurance is valid at the time of reentry. It is crucial to ensure that the health insurance remains valid for the duration of the intended stay.
