So I've gone through the same issue and when I brought it up to my family that I was thinking about studying abroad everyone quickly said no don't do it or you're crazy... etc... basically I made sure I had all the facts... how I was gonna pay for everything, where I would be staying, and that I knew the process for applying. My university was very good about informing students about what they would need to study abroad in whichever country they chose, I told my family basically everything about the process so that they understood. Of course parents are not going to want you to leave and go somewhere far away where they can't get to you within a moments notice. You gotta tell them that you want to live an adventurous life and that this is something you really want to do... to see the world and people (also explain how it will look on resume!) After all this is your life and your experience and they gotta let you live it how you want to live it.
