How to convince parents that I don't want to get married?

Hey there guys. Long story short, my parents sent me to the US a few years back to get my diploma, and now I simply love the freedom and opportunities offered to me in this great country. My parents, however, have expectations. First off, they weren’t all too happy when they found out I wasn’t coming back. In the end they learnt to accept it I guess. I stayed out of their radar for the last year or so, but now, they want me to get married, that too to a woman of their choice ugh. Here i was, getting ready to go back for my first vacation in years, and i get a tip off that my parents are arranging my marriage. it was all i could do to cancel my ticket and plan how i can get out of this mess. I can’t simply refuse their request, as they paid for my coming here, and my tutition. But I just can’t spend my life with some random stranger, pretending that I actually care about my culture. In reality, I am not much of a family man at all. I relish my indepandance and have no intention of getting into any sort of domestic understanding, especially not one that’s arranged.
So what do you guys think? How can I get myself out of this, while not outright saying no in my parents face?
