我帮母亲 2011 7月申请移民 最近AIP了 几个问题如果有知道的朋友 请解释下 ：
1.信上说 WHEN YOU TRAVEL TO NZ IN ACCORDANCE WITH YOUR RESIDENT VISA, YOU MUST APPLY FOR AND BE GRANTED ENTRY PERMISSION.BEFORE YOU FIRST TRAVEL TO NZ, YOU MUST TELL US ABOUT ANY CHANGES TO YOUR CIRCUMSTACES ..... 这句话是不是说 来之前 我母亲还需要申请签证啊 ？
2.现在永久回头签证 是需要几年啊？是需要5年了吗 ？信上是说 AFTER YOU HAVE HELD YOUR RESIDENT VIAS FOR FIVE YEARS THAT YOU WILL BE ELIGIBLE TO APPLY FOR A PERMANENT RESIDENT VISA
