PROGRESS FOR U.S. IMMIGRANTS- 43% ON WELFARE AFTER 20 YEARS: Immigrants lag behind native-born Americans on most measures of economic well-being — even those who have been in the U.S. the longest, according to a report from the Center for Immigration Studies, which argues that full assimilation is a more complex task than overcoming language or cultural differences. The study, which covers all immigrants, legal and illegal, and their U.S.-born children younger than 18, found that immigrants tend to make economic progress by most measures the longer they live in the U.S. but lag well behind native-born Americans on factors such as poverty, health insurance coverage and home ownership. The study, based on 2010 and 2011 census data, found that 43 percent of immigrants who have been in the U.S. at least 20 years were using welfare benefits, a rate that is nearly twice as high as native-born Americans and nearly 50 percent higher than recent immigrants.
