Determining the “other parent” is usually not a problem where there is only the Number
Holder (NH) and one other parent. However, a child may have multiple “other parents”
such as a step-parent, or a divorced natural parent. For payment purposes, a child’s
benefits will be payable for a month only if, in that month, the child has one other
parent, in addition to the NH, who had resided in the U.S. for 5 or more years.
