Original PR of my family (self, spouse and our kids)expired in 2020 and since then I alone had applied and granted RRV till date. Upon next renewal, I wish to also apply RRV for my son who is now 16 years old, so that he can pursue studies in Australia. We are currently in India and he has not been to Australia in last 5 years. Should I wait for my visa to be granted first and then apply for my son or should we apply together as a Group Processing? Kindly advice
