The big fall in income is nothing to do with Brexit, and it's worth saying that international students from within the EU paid the same as home students pre-Brexit.

What happened was a massive expansion to non-EU students paying the larger uncapped fees because of an expansion of student visas to allow (a) dependents to come (b) a route to staying in the UK. It led to over a million immigrants in one year, was massively criticised politically, and so got scrapped. There's no a lot of arguing that we should as a country remove/change the Indefinite Leave to Remain route because those graduates (and dependents) are from January starting to be eligible to apply and stay permanently.
