Hi, my family and I wants to flagpole. We’ve just booked an appointment to do so at the border of Pacific Highway. My dad has already PGWP, but still got an appointment too. The main ones who need the service are me (currently have study permit and want to change for work permit), and my brother and mom they need to extend their visas. I’m not sure if my dad has to cancel his appointment or stay with it and go with us, and also if we really need to cross the border with a car.
