Commitment to live and work in NSW
NSW has nominated you for the subclass 190 visa because your skills are needed in the NSW economy and you have committed to live and work in NSW for at least two years (if granted the visa).
In accordance with your commitment to NSW, you are required to move to NSW:
if you are in Australia, within a reasonable period after you are granted the subclass 190 visa; or
if you are outside Australia, as soon as possible after you enter Australia as a holder of the subclass 190 visa."
