How to compare my knowledge with the IT people in USA?

Hello,
I am from Europe.
I have Bachelor Degree in Computer Science. 3 years of working experience as application developer in Lotus/Notes/Domino. I have the CLP cert. During theese 3 years worked almost everything from hardware problems to network and app development. I would like to come to USA one day (I hope soon), but the problem I have is how can I compare where I am on the job market in the USA. Can I found job at all? What about the salary? Entry level or…?

Thanx
