How Do I Remove Conditions of Residence?
Within 90 days before your conditional green card expires, you must petition to remove the conditions of residence through form I-751. The purpose of the form is to remove conditions on a person's residence if he or she obtained their status through marriage and he or she was married for less than two years before becoming applying for a green card. You have to file a filing fee plus biometrics fee.
Contact an immigration attorney if you need legal advice.
