@pinoysg yun lang naman ang requirement sa EOI for 189. I suggest you push your agent to lodge the EOI for you since you hired one.
pag 190 naman, it depends per state. pag NSW, you need to wait for their invite before you can apply for state sponsorship/nomination.
pag VIC, pwede ka na mag send ng application as soon as you've lodged your EOI. May iba nauuna pa ang application sa VIC before lodging EOI.
