如题,已经帮我怕父母申请了600旅游签证,已经批下来了,但后面才想干脆同时帮他们办付费算了,然后就马上在他们出来之前把申请递交上去。昨天用快递递交的,今天快递给我对方的签名说是文件已经到了perth办公室。但是还没有扣费什么的。我问过移民局,什么时候父母可以出来,他们的回复是Your parents application must be lodged with the Perth office while they are offshore and you need to allow time for it to be received before they come onshore. Please wait until you have received the receipt and they will then be able to come onshore using their tourist visa. 请问有谁知道这边的receipt是指什么?是说他们收到文件的快递收据,还是他们扣款后给我的收据?因为我父母的机票是下周一,我不知道现在只是有快递的收据,是不是表明他们已经递交成功了,还是要等到扣了款才算?
