The International Language

I live in a wonderful neighborhood in Chicago called Rogers Park.
It has been called one of the most culturally diverse neighborhoods in the entire United States.  So, obviously there are many different cultures and peoples running around this area of Chicago.
On the one hand, it makes my neighborhood an exciting and interesting place to live...with the small ethnic restaurants that serve fantastic food to the little mom and pop stores that sell international jewelry and wares, it always makes for a fun weekend.

But, and I know many people are going to think I'm insensitive and hypocritical, I wish everyone would just SPEAK ENGLISH!

I mean really, you're going to come to the United States to live and open a business, but you don't or won't learn the native language of the country?  REALLY?  I think 6 months to a year after someone moves to this country, they should be required to take an exam...written and oral on the english language.
If you pass, great!  Welcome to America!  If you fail, get your foreign ass back on the boat!  And, don't come back until you can hold a conversation...IN ENGLISH!
(Broken English may be accepted...but it will be on a case by case basis.  So, it would help if you were really cute).

I realize I'm ranting.  But, it really infuriates when I call my favorite Chinese restaurant to deliver dinner and the person on the phone cannot speak a lick of english...how on earth are you going to take my order?

I've often thought it would be super funny to get a t-shirt made that simply said, in HUGE letters, SPEAK ENGLISH!...and wear it all over Chicago.  If I knew I wouldn't get shot, I probably would have done it already.
