  1. No, each person is under $10,000
  2. Only the parents must
  3. Yes, the limit counts the group total ✔

Why: For families or groups, CBP counts the total everyone is carrying, not each person's share. Four times $4,000 is $16,000, so it must be reported.

Huh, didn't know that: The rule also covers money you mail or ship, not only cash you carry.
