I recently got a new British Passport in Bangkok. The issueers of the Passport told me it was fine to immediately travel abroad with new and clipped old passport. Then on return go to local Immigration to have the documents transferred. Both Thai Immigration on exiting The Kingdom and returning also had no problem with this. Nong Khai Immigration say this is not correct and refuse to transfer. They say I will have to use 2 passports until I renew extension of stay. Is this correct or are they just being awkward. Any advice or opinion would be much appreciated. TIA

They are being lazy.

Would be somewhat understandable if extension was due soon.

Just travel with both pp

BTW: do you have reentry permit in old pp. Where was it issued?

Who are the 'issuers' that you refer to? Your embassy or an agent?
