If she already presented a permission letter from the other parent at her interview, then she can just carry that letter . 
Is the other parent cooperating or is he MIA?

Children traveling to the U.S.

All children, including infants, must have their own travel documents such as a passport or document from a Trusted Traveler Program to enter the U.S. If you travel or are going to travel with a child, consider taking the following documents:

• If the child is traveling with only one of their custodial parents, they must have a letter of consent, preferably in English and notarized, from the other parent or signed by both parents. The letter should say "I acknowledge that my son/daughter is traveling outside the country with [the name of the adult] with my permission."
• If one parent has sole custody of the child, a copy of the custody document can take the place of the other parent's letter.
• Parents who frequently cross the border by land with a minor must always carry a letter of permission from the other parent
