A Derivative Beneficiary is someone whose petition was filed by being an derivative family member of another applicant. For example. a unmarried child can accompany or follow- to-join the principal beneficiary based on a parent-child relationship. Or the spouse and children of a J-1 visa holder would be granted derivative status as J-2 visa holder. A derivative beneficiary's status is based on the principle beneficiary's status. Generally speaking, if you are the main applicant of a immigration benefits, your spouse and children normally can receive the same or similar status and benefits that U.S. grant you.
