I'm currently have totally 3 years after M.S. graduate work experience, and 2 year can be verified by P.E. from my current company. There is one year experience can't be verified by P.E. (there is no PE in my previous employer), but I'm sure that year is closely related to engineering principle (engineering experience). What should I do about that 1 year experience? I just passed the PE in state of Illinois, but looks like they requires 3 year + MS 1 year experience all verified from PEs. Thank you!
