Qualifying for Green Card
When you married your spouse -- who was either a citizen or a permanent resident -- you became eligible to apply for permanent residence status in the United States, which is popularly known as a "green card." Your spouse filed Form I-130 with the U.S. Citizenship and Immigration Services, acknowledging your marital relationship, which then made it possible for you to apply for a green card by filing Form I-485. If you were married less than two years as of the date of your application, the USCIS issued you a conditional, green card that expires after two years. However, if you were married for more than two years before you applied for a green card, no such restriction exists.
Conditional Green Card and Divorce
The USCIS places new marriages under strict scrutiny. If your marriage was new when you received your green card and you're now divorced or are getting a divorce, the USCIS won't grant you a permanent green card unless you can prove you married in good faith and not to circumvent U.S. immigration laws. If you're unable to do so, then the USCIS will begin removal proceedings and you'll be deported, unless you take certain actions. Typically, you and your spouse must apply to remove the conditions from your green card by filing Form I-751 within 90 days of your card's expiration date. If you are divorcing or already divorced, you can apply to waive the joint filing requirement and file on your own.
Waiving Joint Filing Requirement
Typically, the USCIS only waives the joint filing requirement in three situations: You entered your marriage in good faith, but your marriage ended in divorce or annulment; your removal or deportation would result in extreme hardship; or, you entered into your marriage in good faith, but you or your child were subjected to abuse or extreme cruelty at the hands of your spouse. Entering a marriage in good faith means that you didn't marry your spouse to game the immigration system in order to gain residence in the U.S. You may prove this by showing that you lived as a married couple after you received your green card, by providing such things as a home lease or deed, tax returns, joint insurance and children's birth certificates. You could also submit evidence of how your spouse's actions led to the divorce, such as proof that your spouse fathered a child outside the marriage or police reports and hospital records that detailed abuse and violence that you or your child suffered.
Divorce After Gaining Permanent Residence
If you are divorcing or have divorced your spouse after the USCIS issued you a permanent green card, the fact that your marital relationship has come to an end does not affect your permanent resident status. In other words, you will not lose your green card.
