I am on my one-year extension of non-immigration over 50 “retirement” visa due to expire early October 2019. I realize that if I stay in country I have to report every 90 days. But if I leave Thailand for six months or even 11 months is there any problem with re-entering Thailand or keeping my one-year visa extension active or getting a new one year over 50 extension next year Until October 2020? I have a multi-re-entry permit that expires Oct 2019. Do I have to maintain a permenant Thai apt address while I am out of the country for 6 mos or more of traveling?
