The requirements to become a professional engineer can differ from state to state.
At a minimum, most states require an undergraduate degree from an accredited engineering program (certified by an organization such as ABET) before an individual can be classified as an “engineer intern.”
A MEng degree alone without a qualifying undergraduate engineering degree is not sufficient to satisfy the educational requirements to become an “engineer intern.” In addition, an MEng degree may not reduce the amount of work experience required to become licensed.
