I'm from the UK and soon to be choosing my A-level topics. I'd like to go into a career to do with space, but know little about what jobs there are. Also I'd like to move to the USA, would a job like this be wanted in the USA? (So that I would be able to get a visa). If anybody has any information about jobs in this area such as salary etc. I'd really appreciate it. I also need some information about what I'd have to study at University, and what uni's are good for studying something like this. Space and the Universe intrigues me, so it's something I'd like to do. Thank you in advance!
