Do I Have to Notify USCIS If I Get Divorced During a Conditional Green Card?

Yes, if you get divorced while holding a conditional green card based on marriage, you must notify USCIS when you file Form I-751, Petition to Remove Conditions on Residence. Normally, couples file this jointly to remove the conditions, but if you are divorced, you can still file individually using a waiver based on good faith marriage. 

In this case, you need to provide evidence that your marriage was genuine and entered in good faith, despite the divorce. Failing to notify USCIS or properly file could jeopardize your green card status. Consulting an immigration attorney is strongly recommended to navigate the process correctly.
