I am an EU citizen, and 27 years old. I completed my Bachelor's and Master's in Electrical Engineering in the UK, now finishing up my PhD (in EE as well) in the USA.
I am currently applying for postdoc positions everywhere (EU and USA). I have, for the most part, adapted to life in the USA over the four years that I've been here. However, I am motivated by the idea of doing a postdoc in Europe, partly because I believe the overall culture there suits my personality more, and partly because all of my family is there too. I also want to experience the European way of conducting research (since a Master's in the UK didn't really involve all that much research).
My question is: now that I am still in the USA, and can get a work permit for 2 or so years easily, I am thinking that it would be a good chance to stay a bit longer and experience a postdoc here instead.
In general, I am quite adaptable and I don't have too many set expectations. I just want to conduct interesting research and have a somewhat decent social life to keep some sort of a balance. Money is not really an issue. Also, although I do not like to plan too much into the future (because you never really know what happens), I guess being considerate of the opportunities/prospects a position can offer in the future is healthy.
Given this information, what do you are the pros and cons of Europe vs. USA for a postdoc? Answers to this question probably require some over-generalizing, so I apologize in advance for that.
