I messed up on my days when booking my outgoing and return flight.

My plan was 30 day stamp in passport and 30 day extension.

Giving me 60 days in Thai, but on rechecking my days i have gone over by 1 day = 61 days total. 

What are the implications do i just pay the 1 day fine at the airport or is there grace given when i extend at the privincial  immigration office.

Thanks for any advice

Answer summary

The user has accidentally overstayed their Thai visa by one day and is seeking advice on the implications. Several comments suggest that a one-day overstay is generally overlooked, and it's better not to mention it when applying for an extension. Other users recommend ensuring proper flight bookings to avoid complications and suggest that the exit ticket must be scheduled within the first 30 days. Overall, the consensus is that minor overstays can usually be resolved with a small fine at the airport or may not even be addressed during the extension process.

Keep in mind your arrival day is counted as day 1 of your initial 30 days regardless of the time of day you arrive...

You can go through immigration at 11.45pm the day you arrive and its still counted as day 1

What time is your flight back on the 61st day? If early morning, go through immigration before midnight

The one day isn’t a big deal. Better not to have any overstay but they tend to ignore it if it’s one day. Probably for the very same reason - people miscalculate.

I wouldn’t mention it at immigration when applying for the extension. I’ve never been asked for flight details when applying for an extension so maybe they are not interested.

You also need an outgoing ticket within the first 30 days.

MotivatedFrog4797 FFS! It’s an entry requirement into Thailand. And the airlines often check it too before allowing you to board.

Or you enter on visa exemption, get 30 day extension and pay one day fine.

Or apply for 60 day tourist visa en get extension in Thailand for 30 days more
