Hey Nevyn, I don't see why not- I'm in a psychology department and we have plenty of research assistants and PhD students here who are international students. Do you have a psychology background, i.e. BSc, MSc etc? For psychology most places will ask for an MSc with a significant research component to be considered for a PhD, or alternatively a BSc and research assistant post but then a lot of research assistant posts also go to people with MScs. So if you don't have an MSc, that might be the way to go. If you do one that is officially registered as a research degree then that might help, and then if you still can't get a PhD then a year or two as a research assistant can often lead to a fully funded PhD- I've seen that happen plenty of times in our department! Good luck with it! KB
