Dear Raul,
Thank you for your response.
I have one more related question, if you don't mind:
My 457 was granted before 18 April 2017, and I understood that I'm eligible for grandfathering arrangements when applying to PR via the TRT stream (e.g., can apply up to the age of 50). My question is whether I will be eligible for these special arrangements even if my nominated occupation changed (i.e., my first 457 visa nominated occupation was "Life Scientists nec", and my new occupation, still with the same 457 visa, is "University Lecturer").
Thanks ahead,
Oren
