The department of Homeland Security has declared in 2004 that United States Government had built which they called the Border fence between The United States of America and Mexico. The project would have been finished by the end of 2008 and under the construction in the state of Arizona and California. This border fence has opposed many of the political and human right movement. There are six factors that lead the border fence to become a bad policy in the law of immigration especially to Mexican. The fence cost millions of dollar to build and it help nothing for preventing the illegal immigration from Mexican, furthermore it’s just prolong the overstayed period visitor in the United States that lead to the increase of in state illegal settler. It is also damaging the environment of the surrounding area.
