Yes, would like to see this specific Post about the incident in Pattaya....and the specific circumstances of that particular person in Pattaya. Perhaps he/she may have had prior history with the police/immigration/officials/neighbors/etc.
Gardening in your own yard or maintenance work of your own home?? Where in Thai language does it state that foreigners in Thailand are prohibited from doing such activities??? Again, printed in Thai language, but in English language is fine as would like to find the source of such information or misinformation....
Would just add that it has always been up to the discretion of the Thai Immigration Officer no matter where Port of Entry is, but always good to remind people....
Well, I have used to assist in obtaining U.S. Passports for very urgent/emergency situations (expedited same-day issuance) in order to obtain an appointment for entry to apply for Urgent, Expedited U.S. Passports at federal U.S. Passport Agencies (within the U.S., such as at Los Angeles, Miami, Atlanta, Houston, etc.) and the federal U.S. State Department Duty Officer that you must speak with over the telephone does look up the PNR (Booking Reference #) for those "dummy tickets" "onward travel tickets" as legitimate....
in addition, you can look up, on your own, those tickets/reservations directly on the respective airline's website....
Look, for the vast majority of tourists on a short visit to family and staying with such family (short visit = < less than 60 days tourist visa exemption), and not needing services of, or interacting with the Thai Immigration Office, then not really practical to do a TM.30 Notification, even though it is required by law for anyone staying more than 24 hours at any one location....
However, cannot feign complete ignorance as they specifically asked a question here in this Facebook Group, so there are cases where there are Thai Immigration Officers activiely checking, such as the many cases in Nakhon Si Thammarat for failing to file TM.30
just go by exactly as printed in your passport and also looking at the bottom of the photo page within the Machine Readable Zone (MRZ) will tell you whether to put a space or not as no hyphen/dash are allowed in names....
