US citizenship is extremely valuable and your career opportunities at this stage are likely to be far more valuable to you in future earnings expectations than a few additional percentage points on investments.
In terms of investing, my understanding is that you are best off investing in the US and that there are US investment options open to you (Charles Schwab I believe often comes up as a broker in this area) rather than in the UK.
