REMOVAL OF CONDITIONS
In marriage-based petitions where the applicant's marriage to a U.S. citizen or permanent resident is less than 2 years old at the time the green card is approved, the applicant will be granted conditional residence which is valid for 2 years.
The conditional resident must file a form I-751, petition to remove conditions on permanent residence, within 90 days of the expiration of the 2-year period. If the conditions are not removed, the conditional resident may lose their permanent resident status. If the conditions are successfully removed, the applicant will receive a normal 10-year green card.
The petition to remove the conditions on residence should be filed jointly with your spouse, or with a waiver of the joint-filing requirement which applies if:
You married a U.S. citizen in good faith, but your spouse has since died.
You married a U.S. citizen in good faith, but have since divorced or annulled.
You married a U.S. citizen in good faith, but have since been subject to extreme cruelty by your spouse.
You are the child of a conditional resident and have been subject to extreme cruelty by either your conditional resident parent or their spouse.
Termination of your status and removal would result in extreme hardship.
In some cases, an Applicant may petition to remove the conditions on their residence and file for Naturalization simultaneously.
