There are deep-rooted differences of opinion between multiculturalism and language planning and policy in the United States. It is also true that various discussions and opinions are held and provided over these two issues among proponents and opponents who have been a long debate about them for many years, and it is a controversial issue among minority people and immigrants from abroad, including Asian immigrants. The arguments held by advocates of multiculturalism and language planning and policy are fivefold: 1) multiculturalism promotes acculturation; 2) multiculturalism help promote mutual understanding; 3) well-planned language planning and policy have the immigrants narrow the gap which they are trying to get involved with Americans as soon as possible; 4) multiculturalism and language planning and policy help protect immigrants’ cultures and their languages; 5) a huge variety of culture-centered education and language planning and policy awaken their cultures and languages, which also lead to synergistic effects to acquire the English language. In an increasingly globalized America, English-Plus movement as new language planning and policy plays an important role in resolving the problems facing. Bilingual education and English-only are not enough for comforting the immigrants struggling with poverty and educational inequality.
