Scenario: an American male who has been working in this country for 20 years ( no previous family or links with UK), ( don't know how he managed that either), suddenly decides to wed a British woman. They meet on an internet dating site. She is twenty years his junior, and aged 45, so no prospect of children or wanting them ( I know this before you say it is possible) . I am aware that immigration and working permit rules under much scrutiny presently and being tightened up, especially over the last few months. He is retirement age, and physically limited ( legs). So I guess after 20 years in UK he may want to settle here, and he owns a house in Northampton. She has recently been divorced, and whilst she has known the American for 2 years, he only proposed recently and they did a flit to the US two weeks ago to tie the knot over there after dismissing the idea of a UK marriage. The American hasn't been to his hometown in over 20 years - surprising now? She is a bit dodgey - and not incapable of a few moves to get benefit or loans that she cannot justify. But the main thing is that post marriage they will not live together, and she stated to me that they were flying back from States the day of the marriage, and she was off to do a sport tournament the next day. The link with teaching is that he works in a private school, and apart from boarding in, goes to his Midlands home when he isnt. Is this a marriage or a sham?
