when did you get the last medical exam results? if they were within 3 months by today, you just need to quote the medical paper in your parents' immigration application, in their visitor visa application.
But you need to apply their visit visa as soon as possible, just send the application now for the visa in Feb!!!!
Good luck, you could save a few hundreds NZD :)作者: tingting924 时间: 2012-12-6 21:41:28
