My question is as follows: If I decide to terminate a 2 year teaching contract after 1 year should I expect any problems?

In my contract it clearly states that I have to give a 60 day notice in writing, which I am doing, and I will leave at the end of the school year,July.

I would like to see my students graduate and then move forward, however I would need a release letter for my future employer in China.

Can any veterans see any problems, regarding a release letter, or offer any good suggestions or advice?

Thanks!
