I think it's silly that the applicant's finances aren't taken into account. I make $80,000/yr here in the States, and I have enough in savings and investments to more than make up for my girlfriend's salary...but since she's a teacher, we'll have to wait 3 years before she meets the minimum income threshold (assuming the 25,700 figure) if we want to move to the UK.
I think it's crazy that someone who makes 26000/yr in London with no savings will be allowed in, but we have an immediate denial because she makes 21588/yr. Minimum income requirements that don't take housing costs and cost of living into account make absolutely no sense.
...actually, come to think of it, is it possible to take my savings and annuitize it somehow so I actually can count it as investment income? That would, hopefully, supplement her income and put us over the threshold. Is this possible, and would the UKBA accept it as an income source?
Oh well. Hopefully the minimum income will be set low enough that it won't be an issue. It looks like it's going to be on the high end, but I'll try to stay cautiously optimistic for now.
