So I'm trying to figure out if I need to take the IELTS test or not, but two separate people from the international office from the University of Hertfordshire are telling me that as a US citizen I don't need to take the IELTS and can just have a 1-year degree or more or SAT score and the other is saying that I need an IELTS exam even though I was born in the US, so I'm confused! Will an associate in arts degree replace the IELTS or no? Is an IELTS score also required for the UK visa to study??
