I acquired my green card in January 20, 2010 with an expiry date of 2/23/20. I came back to the Philippines on February 2011. I want to go back to the US next year around March. Do I have a problem?
Generally speaking, a reentry permit is not a guarantee. It is merely an official declaration of your intention not to abandon your green card. Normally, the govt. does not question it. But if there are facts that make them suspect that you either never established or never intend to establish permanent residence in USA, they can take you to immigration court to take away your green card.
