I think it's horrendous and felt sick when I read about it this morning. I'm a UK citizen and have been living in the EU with my EU husband and two dual-citizen children for the last few years. We've been planning to move back to Scotland in the long term, but following this news we've had to jump into trying to move as soon as possible, because we can't possibly meet the new income requirement.
This is more down to the nitty-gritty of the rules than the amount of money itself. When making the initial application for a spousal visa, the applicant's work earnings can only be taken into account if they are already legally in the UK with the right to work. This means that if the family has been living abroad, it falls to the UK spouse to evidence 38,700+ of income for the initial application.
In our case, I've been a SAHM and part-time self employed, so I have a very low income from work. My EU husband actually earns well above the income requirement from his own business, which he would continue to operate from the UK, but this is NOT ACCEPTED for the initial visa application because he does not currently have the right to work in the UK. Under the current income requirement, we are in the fortunate position that we'd be able to meet it through a combo of property rental income and savings, but once it goes up there's no chance. I'd have to find a job paying above the requirement, which would be nigh on impossible with my current work history - I've never earned that much even when I was working full time (and before anyone says 'just do better', I already have a master's degree). It's not like I can just move home by myself to job hunt or do further training in order to 'potentially' earn enough to get my spouse a visa - we have two toddlers to look after and no family help.
I am desperate to move home. We own our own house in Scotland, mortgage-free, and I want to train as a secondary teacher. We would have zero financial trouble. Our children are British citizens and both they and DH speak fluent English. And still, under these new rules, we will be shut out of our own country if we can't swing a move within the next few months. Some people seem to have no clue how stressful this is for families.
