Has anyone ever gone earlier than the 30 day under consideration date? I booked a couple of nights in hua hin and just realized my checkout date is the date I need to go to immigration. Alternatively, what's the latest you can go to immigration ( nonthaburi) to do this. Closing time is 4.30 but I know for original applications the latest is 3pm. Cheers.

It's no problem if you show up a day late, happens to many people accidentally.

Just go the next day after you check out.

I always go early - I did that today, picked up extension 9 days early, The one month under consideration is just to allow time for it's approval, most probably done in 2-3 weeks.

Thanks all. Appreciate the prompt replies. 

Last two years i have been told to come back on exact date mentioned.

 

It's always been ready.
