Into a Support Project

I’m in US and I’m into a Support Project. I was never told abt this project in offshore.
I am an ASP.NET developer and now I’m put in a support project which has nothing to do with .net.
I’m fighting hard with my managers but in vain, I may end up my next 6 months here L
Need to think what to make out of this opportunity (/threat)
I’ve to rethink what I really want in my life and have to have the action plan for that
