Are you talking to me, expat?
I was just replying to the poster who said that she thought we had no experience of immigration, that it was all 'theoretical', to say that actually no, I do have experience and to explain what that was.
We married in 1998. He came here in 1991, was in the middle of appeals etc when we met, we were married about 10 years before he got his leave to remain. It was a total mess from start to finish. It was an extremely complicated one. Including them losing his bloody file at one point! 
And I only outlined it as I say, to say that no, it's not simply theoretical, some of us do have some experience. Because it felt like the poster was saying we have no clue what it's like. Which isn't true.
As to why he didn't leave and apply from the other side, we just followed the advice we were given by the organisation we had asked to help us.
It certainly did take years and years. I have no reason to lie about it. It was a bloody crappy time.
