I am interested in acquiring the PR to Australia. Educational background is in Electrical Engineering (BSc) - ANZSCO 233311, but with 8+ years of procurement experience. What is the best channel for getting my skills assessed (EA or Vetassess)? and if Vetassess then under which ANZSCO? Plus, can I get assessed by more than one assessing body and submit my profile in skill select accordingly? I heard that some ANZSCO do not qualify you for the PR if they are on the STSOL
