I have 2 passports from different countries that are both entitled to the 30 no visa entry.

Can anyone see a problem with my entering 30 days on one then leave and enter 30 days on the other.... alternating to keep to 90 days total of 6 months? ie 50% time on one and 50% time on the other?

Both passports are legit.

Yes, there will be a problem. After entering on passport A and then leaving on passport B, the Thai immigration officer will not find your entry stamp. You have to enter and leave Thailand on the same passport.

No he means enter on passport A leave on passport A..

Enter on passport B then leave on passport B..

Repeat..

Its possible until they catch you.. You are breaking the 90 days in country rule so even though its hard to track you your still breaking immigrations rules..

I'm trying to work something similar, using tourist visas sent for by post (to save a few days waiting around in Laos or Malaysia).

You would have the 90 day problem though, with using neverending VOA's. Tourist visas might possible though, somehow?!?.

fingers crossed i'm wrong, but I do see a problem with entry/exit stamps.

With the 90day in 180day rule I suggest the Immigration authorities are trying to restrict the tourist (not the passport) from exceeding 90days every 180days, So if your name and date of birth is the same in both passports and your mug shot will look the same that they take on entry at an airport then you should consider how the immigration police might react if the computers pick it up and they realise that they are being tricked.

Another bright guy looking for a loophole which will eventually result in immigration auhtorities tightening the rules for all others

Having said that, I think that it is very unlikely that he will get caught if he uses his 2 passports efficiently.

I would not do it at land borders as he might get caught just because the officer will remember his passport and he will not have a corresponding stamp.

At airport points,there is no need for a corresponding pints as so many countries do not stamp the passports.

Maybe it would be best if you used passport A at border A and then passport B at border B. So, use passport A 3 consecutive times untill your 90 days are up, exit on passport A and travel to a different border to enter on passport B and do the same process. Nothing wrong with trying and unless someone else knows, you wont know if you can do it or not untill you try. But, it deffienetly legal atm...............

This might be possible but when enterring at B border with B passport, there will be no entry stamp to the non Thai country and might arouse the suspiscion of the Thai immigration border guy. This will not happen at an airport as you can be coming through transit.

I would not do the switch of passports at a land border and risk being held on the wrong side of the border also the other country might notlike you going out on a passport without an entry stamp......risking problems with Cambodian immigration may not be as easy to resolve as with Thai immigration

I have found you cannot 'flip' passports at land borders (even though this is fully legal).. I had only 2 pages left in one passport but have been stopped from 'clipping' to a new one at Ranong and Sadao over the years.. This was long before the 30 day issues and I had nothing to gain except the efficient use of an empty passport. As I said I understand that both passports are equal and it is a persons right to choose which one to travel on (especially if dual nationality) but no point argueing with immigration.

On air flights it has never been a problem.

I mean you would leave Thai on passport A, then stamp in and out of Cambodia on passport B so Thai could see the Cambodia stamps in passport B, the only problem with that would be if the cambodia officials want to see Thai exit stamp which would be in passport A. Is cambodia interested in checking for the Thai stamps, or is it only Thailand that is interested in checking for other countries stamps.

Doesn't make it a good idea.

I know a guy on a 7 year overstay.

I wouldn't recommend either strategy. LMAO

Fine ??

Dont forget that European price.. Caught altering immigration stamps.. Jailed and died in jail months later.. Thats an aristocrat prince !!

Messing with immigration stamps is one of the dumbest things you can do..

It's not illegal and the onus is on immigration to spot that you've used more than 90 days, two passports or not. There's no question on the immigration form saying have you entered Thailand on a diiferent passport which is still current?
