Uk passport renewal for dual citizen thai
My wife, a Thai national, obtained British citizenship, residency rights and a UK passport in the UK 5 years after we married there.
We have never registered our marriage in Thailand.
She has a Thai passport in her maiden name, and a UK passport in her married name.
Next year she will have to renew her UK passport for the second time.
She will do this in the UK.
I have read that if a person has dual nationality the UK passport issuing authority now (since 2015) ask to see the other passport and will not renew the UK passport if there are different surnames. At the time of the first renewal they never asked to see her Thai passport.
Anybody got any facts or information or advice about this, such as will it be necessary to register our marriage here in Thailand so she can change her surname on her Thai passport before we return to the UK next year.
Thanks.
