but you need to provide evidence as well during the lodgement of file and when they will process the file after 5 years then you need to prove dependency again.
but they will considered you as 18-23 years old . Not more than 23 years.
.....
same like 18 years old dependent, If you add a dependent less thn 18 year old during lodgement, you don’t need pay 47000 dollars for dependent child even when they process file after 5 years. You will be considered as less thn 18 year old.
