Totally open, no issue at all for foreigners to bounce out/back (other than the typical issues people bouncing themselves at the cambo borders have faced in the past)
Ban Laem and Ban Pakard in Chanthaburi province open later than normal. They used to open at 6am - 10PM <(really until about 9PM)
BUT
Now with the "disagreement" going on the thai side opens at 8AM and the Cambo side opens at 9AM <- meaning that's the soonest you can get out of thailand into cambodia 🙂
People from 90+ countries (Australia included) get stamped in FREE for 60 days on the "visa exempt" entry program (which has been 60 days since July 15th 2024)
Once you're here you'd go to your immigration office, get the hand out listing the documents needed to apply for the in country 90 day Non-O visa based on retirement for 2000baht.
You need a minimum of 15 days left on your entry stamp to apply for that visa at most offices. When you apply you will get a receipt that says to come back to the office in 2 weeks. When that time runs out, you return to the immigration office and they ink in the Non-O visa, and a new 90 day stamp.
Then you wait until you have 30 days or less left on that stamp, go back to the immigration office with all new documentation and apply for a yearly "extension of stay" based on retirement for 1900baht. That gets issued on the spot
That's great you Chiang Mai-ese-ians 😮 can use either the main office (which has the 90 day drive thru window) or the immigration location in the Central Festival Mall.
What you do is show BOTH passports when you go to stamp IN to thailand, they will stamp you in on the new passport and make a note that you entered on a "retirement visa/re-entr permit" from the old passport.
THEN
You need to go to the immigration office that issued the extension and get the stamps moved to the new passport
Just so you are clear you file the TDAC (Thailand Digital Arrival Card) using the new passport number 🙂
some consulates are getting wise to people applying and then going back to thailand, they will wait 4 days or so after you applied then email you for EVERY page of your passport including blank pages <- to see if you bailed out of their country or not 😮
We always advise people USE A SERVICE if you're border bouncing from Bangkok because there are many MANY reports that they are NOT letting DTV holders who go to the border themselves bounce out and back the same day.
They can legally make you stay 24 hours in cambodia before they let you back into thailand.
AND
they often ask for a "processing fee" to let you back in OR tell you to just go back to Cambodia and fly in
That "I'm going to save money and bounce myself" scheme rarely works out well with the thai/cambo borders even for DTV holders.
That's why services charge DTV holders more money because the border charges them more to let you out/back and give you a new 180 day stamp the same day
Report back on how it works out for you if you would
