becoming a Professiona Engineer in the US if already P.Eng in Ontario?

If I have my P.Eng in ontario, how difficult is it to become a Professional Engineer in the US?

The US seems to have a more difficult examination procedure; Fundamentals of Engineering Exam (FE) and Principles and Practice of Engineering Examination (PE) compared to Ontario. Both the US and Canada require 4 years of experiencing practising under a Professional Engineer.

Can anyone verify what the requirements are for a Professional Engineer licensed in Ontario to become licensed in the United States (specifically New York State)?
