I am in the process of applying for SENTRI passes for my family (myself, wife, 4 children). On this CBP help page it says:
Application Fee: $25.00 per person (or a maximum of $50.00 for husband, wife and minor children)
Fingerprint Fee: $14.50 (applicants 14 years of age and older)
System Cost Fee: $82.75 per person (or a maximum of $165.50 for a husband, wife and minor children)
Total Fee: $122.25 per person
I am aware I need to create an entirely separate login and application for all 6 members of my family, however after completing the first one I don't see where I am presented the option to link family member applications in order to have the application cost limited based on the parts I've bolded above.
How do I ensure I only pay the maximum $50 application and $165.50 system cost for my family SENTRI application?
