Tell your parents that in under a year's time you could be potentially moving to one of those places, and you need to know if it feels right. If they won't let you go by yourself, remind them, again, that in udner a year's time you will be potentially moving to one of these places, and so it makes no sense to not let you go now (it would be better if you get to know the place first). If they don't let you go, what about going with a friend? Would they be ok with that?
