[求助]有点不明白ICA网站上帮家人申请短期Visa要求的文件的操作性，求解啊！谢谢！

ICA网站上写着可以以local contact的身份帮家人申请visa，然后后面又写了required documents，其中有一个FormV39A--Letter of Introduction，是local contact要填的。这个填好了之后，是用SAVE申请visa的时候要填，还是说家人入境的时候要给啊？那样的话是需要原件么？我得填好了签上字寄回国？

另外还有就是要求里面还要local contact的身份证原件和复印件，这个在用SAVE申请的时候要提交么？以前没有记得有这个要求啊，让家人入境的时候提交也不太靠谱啊，原件呀。。。。

ICA要求的原文是这样的：
