A traveler may be referred to Secondary for various reasons related to their documentation or behavior that raise red flags regarding their identity or motives. When documents are found to be missing or fraudulent, it indicates potential deceit and warrants further investigation. Similarly, if there is suspicion that a traveler could be an impostor, this raises a concern about the identity presented, necessitating a more thorough examination in Secondary.

Additionally, individuals might be referred because of terrorism-related lookouts, where intelligence suggests a potential threat associated with the traveler. This is a critical function of border security to prevent risks to national safety.

Frequent travel, while it might cause some scrutiny in certain contexts, is not inherently a cause for referral to Secondary. Many travelers may have legitimate reasons for frequent travel, such as work or family commitments. Therefore, it does not typically signal a concern that would require additional investigation. This distinguishes it from the other factors, which are directly related to security risks or potential legal violations.
