What are my options when faced with wrongful termination?

I'm 4 months into a 12 month contract; and the company says they will cancel my work Z type

What steps to I take, and in which order re: visa and residency cancellation, finding a lawyer - and where? The online lawyer links don't work BTW. Will I have to leave the country? I seriously doubt that my ex-employer will pass my papers on to another company. Can they be made to do so by someone "up" there? Is there a grace period anywhere in this?
