For reference, 622k students from outside the UK.
The IPaper link I posted above said this would reduce UK university income by 580 million GBP. That is not good.
What I would find useful is how many EU students before Brexit. And Migration observatory says this :
"The number of EU students enrolling in a new course in British universities fell sharply after Brexit, declining by 57% between 2020/21 and 2023/24. Starting in 2021, students from the EU have had to pay significantly higher international fees."

As a positive spin, consider this :
If UK universities get the same fees from EU students as they do from UK students, then universities have no economic incentive to prefer EU students over UK students.
Alternatively, as the migration observatory says EU students dropped after Brexit, will the number of EU students increase again, putting more pressure on places ?
I don't know. But UK students now have lots of options for their studies too. I suppose it really comes down to the universities. Are they providing a service educating , or are they chasing after the students who can pay higher fees ?
