Public Policy on Illegal immigration in US

Immigration in US has been a vital legislative subject for the policy makers since the nation was formed. For instance, the US congress established a program which focused on the US citizens born abroad to become citizens.  This law was enacted in 1875 which prohibited admission of prostitutes and criminal in US. In 1876, the Supreme Court confirmed that the regulation of immigrants was the duty of the government.  Due to rise in number of immigrants, Immigration Services was established in 1879, and this forced the government to process admission of citizens who wanted to become US citizens.
