USCIS requires people to file to remove the conditions on their 2-year, conditional green card. If filing jointly with your spouse or parent’s spouse this must only be filed within the 90 days before it cards expiry date. Filing the removal of conditions application before the 90-day window results in the rejection of the application and filing after the 90-day window could result in the denial of the application. This 90 day rule does not apply for certain situations such as those shown on the following chart from USCIS:
When necessary, an applicant can file after the 90 day period by providing a good explanation along with the application detailing the circumstances that caused them to file late. However, please note that this does not guarantee that USCIS will accept the late filing, though it can help increase the odds.
You can calculate your approved filing window using the USCIS filing date calculator here. In order to use this calculator, you will need to know the expiry date of your Conditional Permanent Residence, which should be listed on your 2-year green card.
Additionally, please feel free to use the following examples to help you better understand how to determine the approved filing window for your Removal of Conditions application.
Example: If Sarah’s 2-year conditional green card expires on July 4th, 2023 (07/04/2023) the soonest she would be able to file her I-751 application with USCIS sometime between April 5th 2023 (04/05/2023) and July 4th, 2023.
