I wouldn't report them, I've heard stories of people who have got their Visa, they've not realized that the visa didn't have multiple re-entry, and so they've been refused entry back into the U.K! Basically they messed up so they ended up getting they're partner in illegally. I am an EQUALIST! I believe we all have equal rights to the worlds riches, equal rights to live exactly any place we want, equal rights to everything from A- Z. People are entitled to live any way they choose, and any place they like. Life will be better for them if they do it legally, but does it really matter that they don't? I mean, what are you going to do? Run after them down the street? Pounce on them? Wrestle them to the ground? And then sit on them and wait for the police to arrive? We're all entitled to a decent life, live and let live I say! Laugh or else your cry! live or else you'll die!
