You do not clearly understand the requirements process. I suggest that you review the state that you wish to become licensed in for their specific rules and regulations. All are similar, but different. The process, in general is as follows.
A. You graduate from an ABET accredited university with a bachelor of science of engineering degree.
B. You petition to take the Fundamentals of Engineering (FE) examination, attaining a passing score
C. You work for 4 years to gain satisfactory experience. Your work does NOT have to be under a licensed professional engineer, however, you must have at least 3 of 5 of your references be currently licensed professional engineers.
D. You petition to take the Professional Engineer examination. If you attain a passing score, the state will then grant you a license to practice engineering in the discipline in which you initially tested.
This is the simple version of the process. Go to
www.ncees.org. They describe the process in great detail and clarity.
This is NOT like a fraternal lodge where someone "petitions" for you to become licensed. YOU are responsible for doing all of the work required for licensure. You have to have licensed PE's attest to your work on your supplemental experience record. The above cited site clearly explains all of this to you.
If your degree is not from an ABET accredited university, there are provisions to address that matter also. Again the NCEES site explains how that works. This is not spooky or complicated-- it is complex, however, if you follow the steps described, you too can become a licensed professional engineer.
