While many languages are spoken in the United States, English is the most common. Although there is no official language at the federal level, some laws—such as U.S. naturalization requirements—standardize English, and most states have declared English as the official language. Three states and four U.S. territories have recognized local or indigenous languages in addition to English, including Hawaii (Hawaiian), Alaska (twenty Native languages), South Dakota (Sioux), American Samoa (Samoan), Puerto Rico (Spanish), Guam (Chamorro), and the Northern Mariana Islands (Carolinian and Chamorro). In Puerto Rico, Spanish is more widely spoken than English.
