what do i need to do

It is unclear from your question as to whether you are a conditional permanent resident (married for less than two years at the time of entry into the States or approval for adjustment of status) or a resident with a permanent green card. If in the latter class, you do not have to do anything as you already have the final green card. If you only have a conditional one, you will have to file for removal of the conditions of your residence status within two years of your having received that card. In doing so, you can obtain a permanent card if you show U.S.C.I.S. that you either had a bona fide marriage although it was ended, or that you were a victim of violence by your spouse, or that a refusal to allow you a permanent card would cause extreme hardship to you, such hardship occurring during the time of the conditional residence.
