Please note this is only for Chiang Mai immigration. They have confirmed that any person who has previously held and OA visa and then extended it inside Thailand WILL NEED health insurance for the renewal. This means if you arrived 3 years a go on an OA visa and since then have been getting extensions in Chiang Mai, you will need to show health insurance at your next extension. For those that do not qualify for insurance or cant obtain it, your option is to leave and then reapply for a NON 0 visa and then get a 1 year extension based on Retirement. Please note that health insurance isnt currently required for the Non 0 Retirement extensions. For any questions contact nico@assistthaivisa.com
