.... and wound up coming here on their Schengen visa.
oh I just knew someone would bite and two of you did. From personal experience, I know but the U.K. visa looked oddly like a schengen one. On at least four occasions I found Ukrainians who got through (keep yer heads down) at least two were here for years and one even got a UK passport for marrying a U.K. national.
How dastardly of them, coming here taking our jobs, marrying our women, becoming British!
