I also have an OA (from Australia), and full Health insurance. I see that the option to have one added year still applies (I did it some years ago), and note that I must add new health insurance for the new "one year", if I do a bounce in/bounce out.
Your last comment - no funds required. Are you saying that the 800,000 does not apply any more on an OA exit/re-entry? So this is different to the O requirement (800k then 400k minimum at all times)?
