Can I enter Thailand after being out for 9 months and staying 9 months previously?

Best to arrive on visa exempt you will be fine possibly to be questioned about previous stay and this stay you will be fine and advised accordingly stay cool

Sure

And if you do have a problem

Just show then screenshot of the folks in this Advice site saying you are good.

I'm sure the IO will then say

" oh for sure -- come on in"

??? Are you seriously asking

No

Depends how long you plan on staying for. If you only have a one way flight might be a problem.

Staying 9 months in the country on your previous visit will be highlighted in the eyes of the immigration officer. You're not a tourist...you're a tax resident. I highly recommend you get at least a proper SETV or METV for your next visit. I wouldn't chance it. I'd also make sure you have the 20,000 THB equivalent in cash and an onward ticket out of the country (even if it's a regional country like Vietnam) to potentially avoid having to return to your country of origin.

If you are coming in from VN and you have been away 9 months I would go for it..its not like you are going to be sent back to the worst place in the World if they refuse you 🙂 just have an onward ticket, hotel booked and 20,000 Baht or equivalent

Hopefully not.

Be prepared to answer a few questions.

Exactly the type of border hoppers Thailand want to get rid of. 9 months in Thailand doing what??? Besides living there….🤨

My boyfriend did the same, even after 7 months outside of Thailand when he gets back in the officer told him that he will need a visa next time. To be safe apply for a tourist visa for your next return. *require your financial proof

How long ago and did you do it with visa runs?

It is 100% depending upon the immigration officer you see at the airport. You can maximize your chances by having at least 20,000 Thai baht (or Equivalent in any currency) on your person, And having a return plane ticket on your person, and having verification a hotel reservation for the dates that you will be in Thailand. Also be very polite and cooperative with the immigration officer.

How did you stay 9 months? Visa exempt with extensions is 90 days. So you overstayed by 6 months? Or you stayed 3 separate times with 3 back to back exemptions and extensions? Details matter.

I would get a single entry tourist visa at the bare minimum

So you stayed over 180 days

depends on…

where you coming from and which visa you have/applying - most 90 days then 12 month extension needed

immigration clamping down on visa exempt extensions… but 60 at moment going to 30 plus 30 extension - so 60 likely to be max soon

The only person that can answer that question is the immigration officer you will stand in front of

What visa did you use to stay 9 months last time?
