I can't speak to the issues you have might as a non-US person. But if you are in college and you are looking to join NASA, or get a taste of what NASA would be like, I'd recommend you try for the NASA Pathways Program. It is a paid internship program that lets you intern at NASA. Also, you might want to have a focus of study, there are various NASA centers around the US (e.g., Goddard, KSC, JSC, JPL etc...). They all have their own specializations, so it might be a good thing to know which center you would like to join in the future.
