As someone who’s wife is currently on a spousal visa (who coincidentally secured her further leave to remain about a week ago), I can see both sides to this, as can she.
As a British citizen, I feel like I have some right to live with my wife in my own country. I’m clearly lucky in that I not only meet the income requirement but can afford the exorbitant visa costs.
On the other hand, it makes sense that I can afford to support my family without recourse to public money and quite frankly, I don’t know how well anyone can support themselves on £18,600, let alone anybody else as well in the part of the UK I live in.
I can understand the argument of this being a ‘tax on love’, but there would always be an alternative to living in the UK - the other country. If living here wasn’t viable for my family, it leaves only the options of living abroad or ending the relationship. Expecting to receive support for my choice from public money doesn’t seem right when there are already so many other areas that need the money for the people already here!
