Appreciate advice on the title topic. I have a non-O marriage visa (expiring in 2017) and my 90-day entry is expiring next month. I plan to do a same day out/in before expiry, probably by air to Kuala Lumpur or Ho Chi Minh. Is this same day out/in permitted and will I get my 90-day entry upon my return flight to Bangkok? If I get another 90 days entry, will this be considered as "staying for more than 90 days" and I have to do the 90-day report?

If your visa is valid you will receive a 90 day permission to stay which can be extended by 60 days at an immigration office to enable you to "visit" your wife.

 

No 90 day report is required.

If it's a multi entry you can do a run each time for 90 days,  on the last one it takes you to nearly 15 months, no need for 90 day reports.

No problem to go out and back on the same day to get a new 90 day entry from your visa.

Thank you all for your advice...much appreciated.
