I have a situation on my hands and have no idea on how to proceed. Any advice will be gratefully received.
We are a multi national company with our H/O based in Switzerland. One of our employees, who is currently working for us in Switzerland is on, what I can only assume, a Swiss Visa. It states on it that it is valid for CH, multiple entries, and is a type D.
We would like him to visit the UK to undertake some training and in the future visit, for work events, and each of these visits will be no longer than a week at most.
Will this be possible on the visa that he currently has or will he be required to obtain another for UK entry. As I understand there is a Schengen arrangement of which the UK is not part of.
