Yes you are wrong
My son did a job for a big company in America he solved thier problem, did another job and thy flew him to America he has been there now for two years he said that the programers there were 2 years behind him, now he is vertually running the show and telling them what to do, it does not prove that a person from another country cant do the job he was offers $100000 a year by the police department to work on the gold sector
He can get into any computer system that he wants to, but he wanted to work in America and show that people from other countrys are just as good if not better.
