Illegal immigration is a major problem in the United States because it causes economic problems and negatively affects homeland security. Illegal immigration leads to an increase in population, which leads to fewer job opportunities, increased pressure on the few available resources, and increased cases of criminal activities in the country. The Department of Homeland Security (DHS) must push for strong policies and measures to strengthen border security and prevent illegal immigration into the country. Illegal immigration to the United States is causing an uncontrolled and unanticipated increase in the country's population. Population growth is not necessarily a problem, but it becomes one when too many people rely on the country's limited resources, such as food, educational facilities, and health care, which are supposed to help poor citizens who cannot pay them. American citizens end up paying for the resources that disadvantaged individuals benefit through taxes (Anderson, 2010). When the population increases due to illegal immigration, the same citizens are forced to pay more taxes to obtain more resources to support unemployed illegal immigrants. With increasing taxes and limited resources available, unemployed citizens are likely to be involved in criminal acts, which significantly affects the country's internal security (Hanson, 2007). Illegal immigration also leads to reduced employment opportunities for U.S. citizens. When illegal immigrants arrive in the country, they need means of survival. As a result, they compete with American citizens for available job opportunities. Some illegal immigrants are relatively more skilled than U.S. citizens; therefore, they are given priority in different companies in the country (Anderson, 2010). Likewise, some companies employ illegal immigrant workers to avoid going through the legitimate employment procedure, which is longer and more costly for the employer. When such things happen, less qualified citizens remain unemployed. With increasing cases of unemployment, some unemployed citizens resort to criminal activities to earn a living (Hanson, 2007). Illegal immigration is also responsible for the injustice of the American criminal justice system. When an illegal immigrant commits a crime in the country, it takes relatively longer for him or her to be prosecuted and convicted than in cases involving ordinary citizens. On many occasions, the prosecutor is forced to seek specific details regarding the illegal immigration suspect (LeMay, 2007). The process of finding out details sometimes takes too long, delaying justice or causing congestion in the criminal justice system..
