I am currently on a Tier 2 Worker's Visa in the UK with a Certificate of Sponsorship from a university as a research fellow. I am basically doing research only, and I miss doing some tutoring and teaching.
What I would like to be able to do is some freelance tutoring on the side, just to keep my pedagogical skills up and make some extra spare cash. I have no idea if I can do this on my visa. Has anyone been in this situation? What kind of small side jobs and gigs can people do on a General Tier 2? I am talking about 1-5 hours a week.
