I'm a junior doing a physics major. I've almost finished the physics major and I've taken more than the required electives, and as I'm not 100% sure whether I want to go to graduate school, I'm considering double majoring in economics. I know that a double major in economics will open more doors for me, particularly internationally, where what you major in seems to matter more in recruiting than it does in the US. As I'm not a US citizen, I'm considering moving back to my home country after graduation and seeking work there. However, I'm not sure whether I want to do a PhD. I know for sure that I don't want to do an experimental PhD; I would prefer to do something theoretical or computational in something like geophysics (or something else equally applied). Double majoring would only allow me to take two or three physics electives in addition to the major and in addition to what I've already taken (I've taken three electives even though only one is required). On the other hand, I've had two summers and a school year of research so far, and my grades in physics are good. Therefore, would double majoring mean that I can't take enough physics classes to pursue graduate school at a top place? I'm still not sure what I want to do after graduation and don't want to close too many doors off.
