exchange visitor must also purchase repatriation and medical evacuation 中的repatriation 和 medical evacuation 是个什么东东？ 是不是指自己必须买的保险之类的？
大概是工资的百分之多少？

In most cases, J1 get a pretty well covered insurance from the employer. I have never heard anybody bought extra above it. It might be a little bit monthly premium, however.

J1一般都是雇主给买保险，如果不给买，你就得自己掏钱买，和工资水平无关，就是酱紫。

另外，如果可以申请h1，千万不要用j1代替，后患无穷。
