I would be wary about having a dual citizenship if you are intending to do security clearance government work in the states. I was actually going to work for the US government during my junior to senior year at school. I had 3 internships lined up. One in Germany, one with a REU doing gold nanoparticle fabrication at an IVY league school, and one with the government. But at the last moment got burned because I wasn't able to gain security clearance. I even did drug tests etc and the process took me several months, I accepted the position many months prior before summer started They never gave me a valid reason but I was grilled on the fact a few weeks prior that I recently renewed my 10 year contract with my birthplace's citizenship. I live in America. The government treats it as a moral gray area for you to work in high secure areas while having a dual citizenship, especially if its recently renewed (which was the case for me, my 10 yr dual citizenship was going to expire around same time I was going to work for US government). The other citizenship I had was a 1st world country as well with very good relations to USA, so it was kind of weird.
