Should English be the USA official Language?

Declaring English the official language is essential and beneficial for the U.S. government and its citizens. Official English unites Americans, who speak more than 322 languages (2000, U.S. Census), by providing a common means of communication; it encourages immigrants to learn English in order to use government services and participate in the democratic process; and it defines a much-needed common sense language policy per http://us-english.org/view/8.   I really did not know this was such a big debate until I started reading more about English as the official language in US.    There are some 31 states have made English the official language for their states.  I just believe that English is important to our society (a common bond) yet having other people speaking more than 322 languages is astounding.    What riches these languages / cultures can bring to this country.    People are quickly learning English while others are quickly learning other languages which will bring us closer in communicating with others.    Now Minnesota is looking at declaring English as Minnesota's official language.
