Thank you vyn. How's your timeline like? Again, Thank youSharing what i did with my 3 children application..
I completed student visa permit upfront for all my 3 children (age 2, 5, and 12). PAOR received Nov 2021 with UCI number for all dependents.
I think you can still submit student visa permit for your children now if not done upfront since application is still in progress. Submit it through webform and/or though courier. Just my thought if it is helpful. Thank you.
