3 years contract in an agency

Hi all! I am new here in this site so please bear with me.

I am a new nurse here in America. Currently I am waiting for my new assignment from my agency who petitioned me from my country. I signed the contract with them September 2014 and arrived in America November 2015. Got my green card a few weeks later. Then I got my first assignment March 7 2016. It was a 6 months contract with a hospital in Arizona and it ended last September 10 2016.

According to the contract I signed with them last Sept 2014, they promised 36-40 hours work load. The contract also states a duration of 156 weeks. I never thought though that it will not be a continuous contract of 3 years work in just one facility. Instead, lately did i found out that we were being marketed as travelling nurses and this means 3-6 months contract to different facilities in states you are licensed to practice.

I am really concerned about my funds. My question is, can this be a ground for termination of contract if your agency cannot provide you employment? Currently, I am waiting for my next assignment for 58 days now and so far no luck. I will need to get myself employed soon if my agency cannot provide me with one because I need to pay my dues. But what is hindering me to apply in hospitals here is my contract with them stating I cannot do that as long as the contract is in effect.

I am an immigrant nurse and I have no idea what are the rights we have as foreign nurse here in America.

Any advise guys? Thanks!
