There has been alot of this on the forum lately so I'm going to copy & paste something I typed recently because I couldn't be fucked considering these things on a case by case basis.

" I was going to say this. They're not fucking around these days with this sort of arrangements. The guy needs to immerse himself in the part & lie to essentially every single person in his personal & professional life & on top of that hope that immigration doesn't smell a rat & declare the whole thing null & void because they will be checking & you wouldn't believe how far they're going these days. And if that all happens can you trust her not to financially butt fuck you with divorce or whatever conveniently after her PR is granted.

Still game OP? I suggest you look both ways before crossing the street
