This bridging visa is not in effect because your Visitor visa is currently in effect. If your Visitor visa is cancelled, you should contact the department immediately. Your Bridging visa may not come into effect and will not allow you to remain lawfully in Australia.
我的理解是, 等公公婆婆现在的签证expire了,就会自动转成BVA。 问题是,他们现在拿的是1年多次往返,每次不超过3个月。 那么现在这1年内600 visa 还没有expire的情况下,他们还需要3个月出境一次吗?
我没有相似的经历,但是仔细看了移民局的解释:
If you still hold a current substantive visa when your BVA is granted, you must continue to comply with any conditions that are on that substantive visa. When your substantive visa ends, the conditions of your BVA will apply.
