I applied for my retirement extension of stay (its official title) while i was on a 30 day tourist visa. Just ensure you start the process as soon as you arrive, so you don't run out of time
A question about a TM30. Does the property owner need to do one of these every 90 days, or do I just use the original one and take along with me and do my own reports ? I have only ever done a TM 47, but renting somewhere in a different place for a while
