The problem stems from the classification of "engineer" in countries other than the U.S. In many countries, an engineer is a person with general knowledge in various fields, basically a maintenance tech. In the U.S. an engineer will have extensive knowledge in one particular field, such as Structural, Electrical, Plumbing, Mechanical. This person has knowledge to design items within their field that meet state and federal specifications including limiting failure of components and the entire project. If you want to be an engineer, you will need to pick a specific field, go to school to get a degree in that specific field. That usually takes from 2 to 6 years, depending on previous college experience.
