While illegal immigrants crossing the border to the United States may come from desperate circumstances, it is unjust, impractical, and unrealistic for one nation to solve the problems of so many non-citizens. Illegal immigration challenges the rule of law. If laws can be broken simply because lawbreakers had good intentions, this suggests that obeying the law is merely optional—that the law is something to be obeyed only when it is convenient to do so. It is understandable that plenty of people who break the law do so with good intentions, but enforcement of the law cannot be reduced to investigations of intentions—it must ultimately spring from concrete actions. The truth is that illegal immigration presents a security risk. Because illegal immigrants are not tracked by any immigration agency and thus remain largely anonymous, it is impossible to verify which immigrants come in search of a new life and plan to abide by the laws of their host country and which do not. A porous border may allow for waves of well-meaning immigrants and their families to seek new lives in a new country, but no country should be blamed for wanting to secure its borders or its territory. An influx of immigration also strains a nation's resources. Understandably, in many cases, immigrants seeking shelter in the United States have left desperate circumstances and arrive seeking support. In a perfect world, this would not be a problem; however, because a nation's resources are finite, this means that the financial and material burden of taking care of incoming immigrants falls on their host county. In small, manageable numbers this isn’t a problem (this is what legal immigration is for) but one can see how a nation tasked with taking care of immigrants from around the world would be burdened beyond its resources if it must solve the whole world's humanitarian problems. Ultimately, we shouldn’t increase our tolerance of illegal border crossings. In order to address the plight of immigrants, maintain national security, and manage internal resources, all policy changes should involve balancing the needs of non-citizens with the needs of citizens before carefully and thoughtfully expanding legal immigration.
