Vietnamese language in the United States

Vietnamese has more than 1.5 million speakers in the United States, where it is the sixth-most spoken language. The United States also ranks second among countries and territories with the most Vietnamese speakers, behind Vietnam. The Vietnamese language became prevalent after the conclusion of the Vietnam War in 1975, when many refugees from Vietnam came to the United States. It is used in many aspects of life, including media, commerce, and administration. In several states, it is the third-most spoken language, behind English and Spanish. To maintain the language for later generations, Vietnamese speakers have established many language centers and coordinated with public school systems to teach Vietnamese to students who are born and raised in the United States.

After several decades of development in a multilingual environment independent of the native country, Vietnamese in the United States has some differences from the Vietnamese language currently spoken in Vietnam, and the community of Vietnamese speakers has consciously tried to preserve those differences.
