Thousands upon thousands of brilliant, motivated, hard working—and legal—immigrants live in the United States. Every year additional highly educated professionals arrive to study and work. Here they make their first attempts at practical use of the English they learned growing up. Now they must speak and write English at jobs and in schools, both of which are highly competitive.
Like the ancestors, or maybe even just the moms and dads of American-born citizens, these individuals have earned the right to be here and have followed the required regulations. Many of them have terrific English. Regardless of their accents, or whether they learned British- or American-style English, they write and speak well. They are excellent people to work with because they bring new knowledge and ideas to the table. They are also fun to socialize with in non-work environments because they bring new knowledge, ideas, and perspectives to the table.
