I am currently a US citizen studying in Glasgow. I want to start a voice-over business online that would be for US clients only. I have looked up the regulations for work as a Tier 4 visa student in my situation. Under my visa, I am allowed 10 hrs of work per week in the UK, and I cannot be self-employed or have my own business in the UK. I see there are ways to set up my own business in the UK, and it looks like it would require a different visa. However, if I wanted to start an online US business where I would be self-employed and paid per project by US companies looking for voice talent for their advertisements, etc., would this be possible while a student in the UK? I am having trouble researching this question online (looked at Gov.uk site, etc.). Would heartily welcome your informed insight.
