Derivative status - step child of F4

[pm5k 129]

Beneficiary has one child, and is married to a person who has a child from their first marriage.  Does that child (step child) qualify for derivative status (child of F4)?

How old was the stepchild when the marriage happened?

Not sure exactly, but maybe less than 6

There were no custody changes or a formal adoption.  The step child is technically raised by both divorced birth parents.

Assuming the stepchild is under 21 and unmarried then he/she will qualify as a derivative. You may need to get formal authorization from the other parent that the child has permission to emigrate before a visa can be granted, so be sure to check this angle with the laws of your country/embassy as to what is required.
