@ginalyn In lodging EOI, you need the to have the positive assessment result and IELTS/PTE. If under CSOL ang nominated occupation mo, then you'll be going for Visa 190, w/c requires state nomination. Hanapin mo kung saang state available yung Nominated Occ mo kasi ilalagay mo yun pag nag-fill-up ka ng EOI.
Be reminded na each state has its own policy and requirements for them to invite you.
And you are required to reside sa state na nagnominate sayo ng 2yrs if visa will be granted to you.
If nasa SOL yung occupation mo, Visa 189 ang para sayo. You can stay at any state with this visa.
Hope this helps.
