that happened to us in China last week. Went to HK and we couldn't get back in, and all of our stuff was at the hotel 🤣 snagged a room for the night and the next flight home in the morning. Having our stuff shipped back by a vendor. Stressful, but not life ending lol.
yeah there are no explicit rules that say you can't comeback to back or what the spacing between stays. That's more just the reasoning why they do that.
I'm glad you go through though, it's a great place to relax (once you're through immigration that is lol)!
It's totally dependant on the officer, and situation. We came in at the end of Dec and did 60+30, went to Cambodia by air for a week, came back and my wife got the same lecture. Did the 60+30 again (zero issues extending) but this time my work visa was approved along with permit. We just went up to china for 5 days, and flew back from HK. Told the officer we are still waiting on my wife's Non O(which is true), he smiled and sent us all through.
We don't plan on needing to file another extension, and my visa is good for two years. But if you plan on doing a boarder run, know there is a chance someone will have ruffled feathers the second and third time you do this. There are some tax obligations that can kick in at 180 days also which is why they want you here on the right visa if it will be for close to or over that stay.
I hold $20,000 USD liquid to cover any emergency expenses for my family of 5. Child birth with emergency C section at the top hospital in BKK (5 day upgraded stay) was about $5,000 USD.
