There will be carnage. The EU citizens will barricade themselves off in a big fortress with high walls they built for themselves and will fight to the death! EU citizen supporters will sneak in food and essentials for them, often dropped from helicopters. This will be punishable but they will risk it. There will be negotiations. EU supporting artists will give concerts at the wall lead by Bono and use the money raised to buy more food and essentials to the people behind the wall. Adele and Lily Allen will set up camp at the wall in protest. Colin Firth will be crying in front of the news cameras and demand rights to EU citizens. I can't tell more, the rest is a bit hazy.
Another HO story: Indian and American couple, but this bit jumped out:
In 2012, when she was home secretary, Theresa May enacted strict spousal visa rules. These requirements, which remain in force today, state that sponsoring spouses must earn a minimum taxable income of £18,600 per annum or have £62,500 in savings. The income of the foreign spouse cannot be included. If the couple has children, the threshold increases dramatically. If the sponsoring spouse is self-employed, as I am, the sponsor cannot include their savings to offset the threshold.
