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.
