Following-to-Join Benefits

This section is for beneficiaries who became permanent residents through a preference classification.

If you were married and/or had children who did not obtain permanent residence at the same time you did, they may be eligible for follow-to-join benefits. This means that you do not have to submit a separate Form I-130 for your spouse and/or children. In addition, your spouse and/or children will not have to wait any extra time for a visa number to become available. In this case, you may simply notify a U.S. consulate that you are a permanent resident so that your spouse and/or children can apply for an immigrant visa.

Your spouse and/or children may be eligible for following-to-join benefits if:

• The relationship existed at the time you became a permanent resident and still exists, AND
• You received an immigrant visa or adjusted status in a preference category.

If your family member falls into this category and you adjusted to permanent residency in the United States, you may submit the following:

• Form I-824, Application for Action on an Approved Application or Petition
• A copy of the original application or petition that you used to apply for immigrant status
• A copy of Form I-797, Notice of Action, for the original application or petition
• A copy of your Form I-551 (Green Card)

If you are in the United States and have not yet filed to adjust your status to permanent resident, you can file Form I-824 with your Form I-485, in which case no supporting documents are needed other than those submitted with Form I-485.

If you received the immigrant visa overseas, you may contact the National Visa Center (NVC) for follow-to-join information. Send your inquiry by e-mail to [e-mail] or by writing to the National Visa Center, ATTN: WC, 32 Rochester Ave., Portsmouth, NH 03801-2909.
