Paging Lou Dobbs

Haven't looked at the study myself, so put this in the category of "confirms what I already thought," but as someone who lives in a city which still has plenty of white ethnic enclaves I've long been puzzled by the widespread belief that today's immigrants are somehow "different," aside from the skin color of some of them.

Immigrants of the past quarter-century have been assimilating in the United States at a notably faster rate than did previous generations, according to a study released today.

Modern-day immigrants arrive with substantially lower levels of English ability and earning power than those who entered during the last great immigration wave at the turn of the 20th century. The gap between today's foreign-born and native populations remains far wider than it was in the early 1900s and is particularly large in the case of Mexican immigrants, the report said.

...

The report found, however, that the speed with which new arrivals take on native-born traits has increased since the 1990s. As a result, even though the foreign population doubled during that period, the newcomers did not drive down the overall assimilation index of the foreign-born population. Instead, it held relatively steady from 1990 to 2006.
