My husband and I are on the list, waiting on 804 Aged Parent visas. We have 2 sons both now Australian citizens and a grand-daughter born in Australia. Our passports are due for renewal this November, so our question is this: Are we required to keep our passports active while we wait for our sub-class 804 visa to come through, or can we let them lapse? We have absolutely no reason or desire to ever go back to the UK. Hoping someone can clarify this.
