I doubt they are refusing to assimilate. It just takes some time to learn another language.
My point in my earlier post is that it takes A LOT MORE TIME, if ever, when one has no initiative or motivation to learn because they're being SPOONFED their own language instead at everything from McDonald's menu boards to blowdryer instructions.
"I doubt they are refusing to assimilate."
There are a large number of Mexicans who come to the United States to earn money for several years and then move back to Mexico. They have no interest in learning English or assimilating in any other way.

And courage. I worked with a lady from El Salvador. When I had a Spanish only customer on the phone I asked her to give me a hand. She handled it well until she needed to take that customer's data. She couldn't spell the name Rodriguez!!! But luckily I was there for her because even I know how to spell it.
