I was not going to reply but upon reading the post... I just had to. I too am not american by origin but have lived here all my life except for the High School years. I did those grades in my country of birth. First, I will say I do not own a cert but have worked in the field for years. Working around " American" tech pro the only dif I see is just that... I will do what it takes to get the job done versus trying to find an explanation to the problem. In a nutshell, it comes done to problem solving and not brainstorming. A lot of cert. pros look first for a reason to the problem while most foreigners look for the solution first.
