You might try getting a carer job in the UK as the basic level of undergraduate training means that you won't be able to gain HPC registration in such a short time frame. A magazine called "The Lady" (http://www.lady.co.uk/ladymainframe.htm) has numerous ads asking for assistance. You might be able to get a copy sent to you as they are not on their website as yet. Perhaps on of these positions might fit something you are interested in?
With a longer term view, studying a post graduate course in the UK might more easily lead to HPC registration than any other route. Best of luck
