MBA School Preference: Abroad or local?

Hi, I’m Frank of California. I have already taken my GMAT and I scored 680 which I believe, is not a bad score. I was thinking it would be better if I enroll in a top MBA School abroad but I have to consider things so it hinders me to decide easily. I am single but is a breadwinner and I look after my parents at home. I wish I could get some suggestions from you guys.
