You think? Where's the proof.
I just checked the Netherlands and it costs 237 euros to apply for a non-eu spouse visa. They have an 18,000 euro minimum salary, but there is an alternate route called 'verification against eu law' which has a much lower threshold. It's significantly easier than applying in the UK.
Based on Theresa May's previous attempts to raise the threshold to raise the threshold to £25,700, my guess is she'll go for a similar amount, likely more (and with kids that threshold goes up to £37,000 for one kid, £49,000 for two).
This combined with the upfront costs of the visa fee (£2k) and IHS surcharge (which will be £1,800) will prevent the majority of people from bringing over non EU spouses. And then there's the cost of FLR(M) (another £3k - though this'll likely be more in a few years) and ILR (£2.3k).
I don't think many people will be able to afford this, effectively penalising you if you made the 'mistake' of falling for a non-eu partner.
I sincerely hope EU residents won't have to go through this bullshit, but I wouldn't put it past May.
