Traveling back with visa extension in cancelled passport?

[JackGats]

As a further reason to get a new passport early, let's not forget the 6-month validity rule. Even though it would seem Thailand did not insist on that, there's always fear the airline could.

 

My coutry now issues passports that are valid 7 years.

 

As someone rightly remarked above, passport deteriorate quickly in TH, what with all the stapling done inside and the fact that milling about with foreigner's passports is a national sport in Thailand.
