Reasoning for Legal Immigration laws.
Vetting and National Security
The primary reason for legal immigration laws is vetting. Without a legal process, a country has no way of knowing the background, medical history, or intent of the people entering.
Vetting: Legal channels allow the state to screen for infectious diseases and, more importantly, criminal or terrorist ties.
Accountability: A legal record of entry ensures that the government knows who is in the country, which is essential for taxes, census data, and emergency management.
The Integrity of the Social Contract
Societies function on a "social contract"—the idea that citizens and residents agree to follow the law in exchange for the protection and benefits of the state.
The Reward for Law-Abidance: If those who bypass the law or commit crimes are treated the same as those who wait years for a visa, the incentive to follow the law disappears.
Public Safety: Deporting non-citizens with criminal records is the ultimate enforcement of this contract. It removes individuals who have proven they are unwilling to respect the safety and property of the community they joined.
Resource and Economic Stability
Every country has a finite "carrying capacity" regarding its infrastructure.
Predictable Growth: Legal immigration allows a government to plan for how many new seats are needed in schools, how many beds in hospitals, and how much housing must be built.
Labor Market Balance: Laws allow a country to bring in people with specific skills that the economy needs, preventing a sudden surplus of labor that could drive down wages for the most vulnerable domestic workers.
Conclusion
Ultimately, legal immigration laws exist to ensure that migration is an asset to the country rather than a source of instability. By deporting those who enter outside these rules—particularly those who commit further crimes—the government fulfills its primary duty: protecting the safety and the legal rights of its own people.
