Let’s take a step back for a moment.
I am more cynical than @FarEast; if Turing funds are constrained to well defined criteria, saying that factually isn’t political. My university publishes the criteria on the GoAbroad website. I do agree with her that management by Capita is a bad omen and, as I said earlier, that visas are out of the university’s control (although a good central GoAbroad team can be very helpful). I agree with PPs who think the lecturer was not clued in
Turing funding is also not guaranteed through 2026-27 many places, which is the relevant frame for OP’s DGD.
It is awful to hear of maintenance loans being cut back when students go abroad. However, are PP’s DCs not getting a big tuition break for the full year abroad? It’s 85% or over £7500 for Home students at my university, and this is typical. Without defending the loans situation, this should help.
Those on a student visa can work part time virtually everywhere in the world. It is more typical in many countries for students to do this than in the UK.
@TizerorFizz is correct; British can still work in the EU. They just need the proper visa and this usually entails having a firm job offer. The company must successfully make a person-specific argument, so the bar is higher than it was, but it is not impossible. It’s done for postdocs routinely. A few countries like Germany offer a limited Job Seekers visa.
Again, I have never heard of anyone actually failing to get their student visa. I think there may be enough low level hostility towards the UK since Brexit that our students suffer from being relegated to the bottom of the admin pile, but ultimately one of the great things about Study Abroad is that governments worldwide recognise its value and support it
