Can my travel companions use CLEAR Pass for CBP Mobile Passport Control ?

Each time you use the app, you can add up to 12 family members traveling on the same flight.

For this purpose, members of your family unit are defined as:
-people who are related by blood, marriage or adoption;
-people who lived together in one household at their last permanent residence
-people who intend to live together in one house hold after arrival in the United States.
