In my school, we have a significant number of new immigrants from Hong Kong, Iran and Russia. These students are completely immersed in regular English speaking classes. Yes, it is tough for them, but they learn fairly quickly and end up doing quite well. We have minimal ESL support available, and none of the teachers speak any other language except English (and maybe French). I've often thought that a more intensive opportunity to learn English may be beneficial, but never with a teacher speaking the native language...that's too easy! and leaves everyone open to neglecting to speak English! I think you're right about political correctness......enough said.
