Why is failure to integrate any less valid a reason than a troubled childhood, drugs, or just simply personal disposition?
Am an immigrant to the US. I learned passable English in less than one yr. I started working when I was 12 yrs old by delivering newspapers, the Honolulu Advertiser in the morning and the Honolulu Star Bulletin in the afternoon. In my teen yrs, I work nightshift janitorial at the IBM building downtown Honolulu. In high school, I learned how to fly before I got my driver's license. After I got my US citizenship, I joined the USAF. As my avatar shows, I am a Cold War veteran on the F-111 and Desert Storm veteran on the F-16. The only criminal records I have are traffic violations, which everyone have.
So you tell us what is the real problem here.
