What happens if I miss my immigration reporting date in Thailand by one day?

As a general rule you HAVE to show up on the date in your passport. That's the date your file is sitting on someones desk waiting for you to come in.

IF you can't make it definitely go to the immigration office OR have your employer call them to see what IF anything can be done.

I know in BANGKOK if you miss a return date on an under consideration stamp you start ALL over again with what ever process you're undertaking. They cut no slack on it up here.

Good Luck, GO to the immigration office yourself OR have your employer contact them to see what can be done.

Ring and ask... Tell them your predicament.

... then do what they tell you...

Note.... One day late means you don't have a valid visa...

Go the day before and if the authorisation is not through explain your predicament & see what they say

You should report on the date they give you. Not sure what happens if you dont. Maybe restart the process. It's up to the IO.

Suppose it up to imm officer.but rember my mate had same proplem in bkk.asked about it and was told know leeway.
