Generally you need to file an I-131 re-entry permit to be away from the US for over a year. Your conviction could also create problems for you when you try to re-enter the US. Consult an immigration attorney.

There is no such thing, but you may be referring to a re-entry permit, which allows some prolonged absences from the US without abandoning your green card. I am concerned about your conviction though as it may create problems at the border when you are coming back. I would recommend consulting with an experienced attorney before you travel.
