I don't know what the numbers are for CPS, but this Washington Post article says that an estimated 10k classroom teachers in K12 are immigrants who have been recruited here to teach, usually under H1B visas. And there is no upper limit, according to the article.
How many are there in CPS, and what's their experience and success rate, I wonder? If you read the article, you'll see that some struggle with classroom management and cultural issues, but that they generally don't quit as fast as US born new teachers.
