International student dilemma

I am currently a sophomore but I realized I can graduate an entire year early due to having many AP credits. However, graduating early possesses difficulties as I am an international student, so my OPT would expire before I even begin full-time... any advice on what I should do? Some of my thoughts: 1. Don't graduate a year early - however, it seems like a waste of $60+K to spend another year in undergrad 2. Pursue a one-year Masters program (MSF?) in place of my senior year - are there any such programs that I can fit in between my hypothetical SA internship and FT start date? 3. Study abroad for senior year? Less boring/more meaningful than remaining in the same undergrad school for four years...
