Language Skills Predict Integration Success
Observing Colorado refugees over a period of 5 years, the Refugee Survey & Evaluation (RISE) Study finds a correlation between a refugee’s language proficiency level and integration successes. Quote: (…) lack of English ability was pervasive among those with low integration. … Lack of English kept many with low integration isolated. As a result, American culture confounded them. Specifically, they had little direct experience or support from others in understanding and negotiating educational, social, medical, and government systems.

Refugees Learn English Over Time
After living in the country for more than 10 years, 86 percent of Somalis speak English at least “well,” and 61 percent speak English “very well” or exclusively. Among Hmong who are in the United States for more than 10 years, 67 percent speak English at least “well,” and 43 percent speak English “very well” or exclusively.

English Skills Pay Off
Working-age LEP adults earn 25 to 40 percent less than their English proficient counterparts. While less educated overall than English proficient adults, most LEP adults have a high school diploma, and 15 percent hold a college degree. LEP workers concentrate in low-paying jobs and different industries than other workers.
