What is the significance of establishing citizenship during immigration checks?

Establishing citizenship during immigration checks is crucial because it directly determines whether an individual is legally allowed to enter the country. This process assesses whether the person has the appropriate documentation and status to cross borders, such as a valid passport or a visa. By verifying citizenship, authorities can ensure compliance with immigration laws and maintain national security. This verification helps to differentiate between lawful residents and those who may be attempting to enter without proper authorization. Consequently, it safeguards the integrity of a country’s immigration system, which is vital for regulating who can enter and under what conditions.

While quicker processing times and enhanced authority for border agents are advantageous outcomes, the primary and most significant function of establishing citizenship is to ensure each individual's lawful entry. Legal immunity is not a benefit that arises from this verification.
