My 2nd extension of my marriage visa is due 23 January and my UK passport expires 16 August 2016. I've read about transferring stamps to new passport in other posts from which I assumed you don't need a full year left on your passport to get the years extension. I met someone who said he had an issue with retirement extension (although he had less than six months) at Korat immigration telling him he needed the full year left. This is my office so would be grateful of clarification. Any other points I should note re this gratefully welcomed. I understand that I need letter from embassy requesting stamps transfer to a new passport of my original assumption is correct ?

Can I use same old photos of us in/out house as last time?

If you apply for an extension it will be dated up to but not beyond the passports expiry date.

When a new passport has been obtained in addition to requesting all relevant stamps from the old passport be moved to the new an NEW application will have to be made for a NEW extension of stay .................

You need a new passport, definitely need a full year for a year visa, lots of help on here about getting a new passport in BKK, simple process but needs 2 trips to the city

If you think you can get a new passport by 23 Jan it would be preferable to get one.

If not your next extension would be valid until 16 Aug.

Enough time to get a new passport before extension due.

As previous post says, you can go with the current passport, but just gives you one more trip to immigration in August.

Nothing won.
