Can I switch from a Non-O visa to a 60-day tourist visa if my application is rejected?

Many get away with it some don't. Both the airline and immigration can see your departure dates so you may get away with both, one or neither. Book a cheap throwaway.

Why everyone chooses 88 ? Because the max is 90 and leeway? Or something else? (Cheaper flights?)

If rejected and you have time put in for a 30 day tourist asap. Can always book a throw away ticket to say Laos then get the 30 extension.

Rumours are they are announcing visa exemption back to 30 days this week.

You can do it and may get away with it - many do.

But, your onward travel should be within the first 60 days.

Airlines can be particularly picky with this as they carry the cost if you are immediately deported.

For the non O (for retirement) you don’t need an onward ticket. So, you’re fine if that is granted.

What is really important, and you haven’t stated this, is your recent travel history to Thailand. If you have been a frequent visitor with long stays then you may be better off getting the SETV; it’s not guaranteed but may be stronger than visa exemption. The same 60 days still applies for onward travel.

Yes, probably

Visa application asks for "intended" date and flight number.

Your Non-O will not be rejected if you are over 50 and have the financial proof (>=B800k or B65k/month income).

Travelled from Paris to Bangkok last January with a return 88 days later with the intention to extend by 30 days. Never questioned at Paris or Bangkok.

What Non O visa are you applying for ?

I did E visa 60 days before I left I have return ticket 88day I got 30 day extension at immigration. I was questioned at airport told them I get 30 day extension. All good 👍

Lynnette Munoz surely the return ticket is proof of intending to leave.

I arrived on July 10 th on 60 day exemption and have extended it for 30 days for a 90 day stay. Aussie Citizen .

I’m hoping to do this I have flights booked and return flights hopefully stays 60 days visa but I’ve got 6 days overstay would I be easily be able get extension for the remaining days over any advice appreciated

You can travel on a 60 day tourist visa or on a 60 day visa exempt/no visa. You can extend both. If exempt entry with NO visa reverts to 30 days the 30 day extension will only give you 60 days. As others have said, the airline are your first hurdle because they may ask for proof of leaving.

I have done this in the past many times, Emirates did question me once as my return was outside the 60 days but I explained I would get 30 day extension.

To cover my arse so to speak one time I booked a flight with air Asia to Vietnam within the 60days for around £28.

Never used it but just incase Emirates or thai immigration questioned it.

You would more need to worry about your airline letting you board, check with them
