I appreciate the thorough response. I also understand that rules aren't personal, but they do have real effects on real people. I often visit the UK visa subreddit, and it sucks to read about situations like a parent not being able to attend their child's graduation because the immigration office doesn't believe they'll return home.
My EUSS application was rejected because I didn't have proof that he was added to my insurance. Where I'm from, that's not even a thing. They don't ask for extra documentation, and they'd rather deny the application and make you apply and pay again. Or like when my friend got a letter about her pending deportation, and the immigration office later said it was a human error.
One British friend of mine wants to move back to take care of his mother, but he can’t bring his wife with him. So they’ve decided to stay abroad and continue teaching at an international school.
None of this really matters on a government level. It's all just numbers. A few Brits unable to come back, a few families split, a few couples divorcing, and it's no big deal in the bigger picture. I get that. But on a personal level, I still wish the system were different and they had an alternative way to fight the issues. But this is just a personal rant. Same in many other countries.
I also think some of this is just for show. For example, when the income requirement for UK citizen family visas was raised a while ago, it felt more like a publicity stunt, a way to say “look, we’re doing something,” even though that group wasn’t really the main issue.
Personally, I think the UK made a mistake years ago by having looser immigration rules for EU citizens compared to other EU countries. In several, maybe even most, EU nations, EU citizens can stay for three months, but then they must register and show they have grounds for residency. Who knows, maybe some of this could have been avoided.
