A friend wants to take his wife & two children to UK for 2 month's vacation later this year. VFS have already granted Visitor Visa for his Mrs, but say his children, 6 & 11, who have Thai passports must have UK Passports. I told him this is a load of Bo11ox, but they insist. Is this correct?
He is in the process of applying for UK Passports for them, but that will take a long time.
If they have UK Passports, can they then enter UK with UK Passport, and re-enter Thailand with Thai Passports? Cheers.
