My Thai wife recently returned from the UK and entered Thailand on her British passport receiving the usual 30 days. Her Thai passport has expired which she will renew whilst in Thailand.

In the meanwhile my wife will require an extenson in her British Passport.

My question is, to which immigration office (Chaeng Wattana Road is nearest) does she need to go to?

We intend to holiday outside Thailand in June and then she will be able to cancel visa stamp in passport and re-enter on her new Thai passport.

You should be able to get a new Thai passport and then go to immigration and get her "entry" transferred into the Thai passport. Then you won't need to worry about extensions.

British passport needs to be valid until we depart Thailand in June, therefore an extension is required.

There will be no problem with an extension.

Once extension is granted, in June, my wife will depart Thailand and therefore use her British passport and use her new Thai passport to enter say HK and use her Thai passport when she returns to Thailand.

My question was, to which immigration office to apply for extension?

If you are in Bangkok you use Chiang Watanna. She could have returned on the expired passport and avoided this issue (in case it happens again).

She can not get her entry transferred into her Thai passport from a UK passport (as you know).

You will only get a 1900 baht 7 day extension with a red stamp "must leave within 7 days" on a 30 day exemption. I'm not sure why you think there will be no problem with an extension.

(You really are better off transferring her entry stamp to het Thai passport.Edit: you can't. You can only transfer between two passports of the same country.) If she can't get her hands on her new Thai passport within 30 (+7 if you take that route) days, you will need to do a border run for 15 days, an airport run (go somewhere turn round and come back) for another 30 days or a visa run (pick a neighbouring country to get a tourist visa 60 days extendable to 90) to get you to June.

A Thai national will easily obtain one year extension of stay when here on a foreign passport.

I knew you would be able to answer my question.

Many years ago she used her British passport to enter Thailand and she received, as you say, 1 year extension.

Next week on my way to Chaeng Wattana.

Many thanks
