UK immigration

[gravity101]

I have to go back to the UK for my mothers last days. My Thai wife and my kids(with dual passports) will travel behind me later. She was just issued a 2 year visa, just wondering what i need to plan for when she arrives in the UK, she has been 4 times before and has always had a grilling and I have been summoned to her at passport control to verify her story. This time I won't be with her. Is there anything I need to be aware of? She did state on the visa application that I would be accompaniying her and my kids, but the plan has changed. Will it be an issue, any experiences?

 

EDIT: We have no return flight booked because of rhe circumstances.

Write a short letter describing what you have said above as reason for entry. Include your contact details etc. and invite the officer to call you if any questions. This is what I do when my Cambodian GF comes to visit me in the UK. She then gives it to the immigration officer on arrival and no issues at all. They never call me. It would be a good idea to buy return tickets (date changeable) as she may encouter issues with the airline check-in when departing Bangkok.
