What do I have to file paper wise to leave the country after the divorce? Can i still enter U.S. for travel?

You have a conditional residence card which will expire at the end of two years. The best course would probably be for you to notify U.S.C.I.S. in writing that you are divorcing, have no intention of filing an application to remove the conditions on your residence, and will be returning to your home country permanently. I suggest that you send such communication with proof of delivery. That may prove useful to you when you either apply for a visitors visa to enter the US, or if you are from a country under the visa waiver program, when you enter the country and are inspected by Customs and Border Protection. Whether you are able to file for divorce and sign it in your home country depends upon the law in your home country since you do not appear interested in living in the US anyway.
