Seems like the most likely way that could happen is if an immigrant with a non-US BS in civil engineering (not accredited by ABET or a mutually recognized accreditor listed at http://www.ieagreements.org/accords/washington/signatories/ or http://www.abet.org/global-presence/mutual-recognition-agreements/engineering-bilateral-engineers-canada/ ), possibly with an MS or PhD in the US (not generally ABET accredited), wants to get a PE license.
