Should I move to US?

Hi All,

I have 5.5 years+ in IT and today I am drawing a good salary in Chennai. I get offers from US to join on H1B visa. But all the consultants offer the starting salary around 60K-62K p.a. That is like starting my career again from scratch.
Should I move to US? I have never been there before. But I know this salary could be bad if I consultant send me to California (as it is expensive) but if it is some other state, it could be good offer.

Thanks, Gaurav
