Why are you leaving Thailand...is it for good or do you intend to return,,,and especially to you intend to return on your curent (entension of) visa.
In other words,,if you are on some kind of extension of your current visa...either for retirement, marriage to a Thai. an EDucation visa, a Non B with a Work Permit...these are all things that require you to do 90 day reporting.
When you leave Thailand, and are stamped out of Thailand at immigration, your exiensions of visa are canceled...and your current extension is voided.
The way you avoid this is to purchase an exit-rentry visa at your local immigration before you leave,
If you don't do this, when you exit your visa extension is cancelled at that time.
Then. when you do return...without a visa (you're current extended visa having been cancelled by your exit from Thailand)...if you qualify you'll only get a 30 day entry stamp (if by air) or a 15 day entry stamp (if by land border).
I'm assuming here that the actual VISA...the one you originally entered Thailand on and that you recieved at a Thai consulate outside of Tailand, is now expired....and that's what you got the extension for.
In my particular case my original visa expired on 15 October 2011...but I recieved an extension of that based on retirement until 15 October 2012.
So now, if I want to leave Thailand for a few days, I must purchase an exit-rentry visa to keep my extension valid.
IF that, or something similar, is also your case...you need to also get an exit-reentry visa also.
If that is the case, then before you leave you should:
1. Do your next scheduled 90 day reporting and
2. At the same time get and exit-rentry visa...to keep your extension alive which will "reset" your 90 day reporting clock to day one when you re-enter Thailand.
Now, for all practical purposes, if you're not planning to re-enter Thailand....90 day reporting is practically meaningless.
But if you are intending to return....you need to go to your local immigration...and do those two things.
Otherwise you may be in for a very unpleasent surprise when you get only 30 days on your return...and then find your visa extension was cancelled by your leaving Thailand without an exit-reentry visa.
