Many pregnant women cross borders to take advantage of the fact that if the baby is born on US soil, it will be a legal citizen. This involves medical costs, benefits for the child, and much more. Even more, illegal migrants come to work in the United States. They are willing to work for a low wage which benefits companies by allowing them to reduce overall labor costs. “In 2007, the percentage of undocumented workers employed in the construction industry reached 18 percent, making it the country's largest source of employment for illegal workers” (Hanson 2010). If these immigrants arrived legally, even if the process is long and difficult, they could work for a better wage as they work toward citizenship. Take one group of migrants for example: “Recent decades have seen a dramatic increase in U.S. immigration, especially from Mexico. Mexican immigrants are the largest national origin group living in the United States. By 2005, approximately 11 million Mexicans had immigrated to the United States and represented 31% of the foreign-born U.S. population” (Donato 2008). This particular group alone has had the greatest impact on immigration to the United States of America. Enforcing policies and tightening standards could help solve this problem. Making deportation standards realistic and limiting the amount of people who can enter the country to work could help significantly. This will allow a migrant the opportunity to not only become a citizen, but to protect their human rights which likely do not exist in the country they have migrated to.
