A “Conditional” Permanent Resident Visa is given when at the time of the interview at either USCIS or a U.S. Consulate the parties were married less than 2 years. The Conditional green card is itself valid for 2 years and the Conditional green card status expires at the end of the two years. You and your wife will need to file Form I-751 to remove the Condition. USCIS will want to have copies of documents to prove that you and your wife are still married and residing together. If the Condition is removed by USCIS, your wife will be granted a full 10 year green card and full permanent resident status. If she does not file Form I-751, then she will be out of status and could risk being removed (deported).
