Filing after Divorce or Annulment ©MurthyDotCom
A conditional permanent resident with a marriage that was terminated due to divorce or annulment must file for a waiver of the requirement of the joint filing of Form I-751. To obtain an approval of the I-751 and be granted unconditional lawful permanent resident status, the conditional permanent resident spouse must be able to show that s/he entered into the marriage in good faith.
The person seeking permanent resident status should expect to undergo an interview at the USCIS about the marriage. The USCIS will closely scrutinize whether the marriage was bona fide at its inception. The USCIS will review the divorce decree and complaint for matters that may be reflective of whether the marriage was entered into purely for immigration purposes or to perpetrate fraud against the United States citizen spouse or the USCIS.

If the USC spouse and conditional resident are separated or have initiated divorce proceedings at the time the petition is due to be filed, the USC spouse and conditional resident may still file a joint petition if the USC spouse is willing to sign the petition. If the USC spouse is not willing to sign a joint petition, the conditional resident is not eligible to file a petition requesting a waiver of the joint filing requirement based on divorce until the divorce is final, unless abuse is the basis for such a filing. However, conditional residents should file a good faith marriage waiver with a hardship claim even if the parties are not divorced prior to the expiration of conditional status. This will preserve the right to reassert the good faith marriage waiver after the divorce. Claims must be properly raised before the USCIS before they can be put before the immigration judge.

The two requirements for the waiver under consideration are seperate, they are not two parts.
Good Faith
In most cases, the conditional resident will file for a wavier based upon good faith. Here the non-citizen must show that he or she entered into the qualifying marriage in good faith at the marriage’s inception. Both parties should submit extensive documentation to support the good faith commitment.
Extreme Hardship
Here the applicant must demonstrate that extreme hardship would occur to the non-citizen if the waiver is not granted and he or she is forced to leave the country. Hardship must be more than the normal results of departure and usually involve emotional, psychological, financial and educational problems.
