As a nation, the US is benefited from a population that is proficient in communicating in English. As individual people, citizens in the US are benefited from multilingual proficiency.

I strongly believe that all immigrants to the US should be proficient in English. If not, they must attempt to learn English once they get here.

Having government forms printed in foreign languages, and government employees be proficient in foreign languages is a great tool for transitioning immigrants to life in the US. However, these transitional tools should not become a crutch and excuse to not assimilate to this nations standard language: English.
