目前的J只剩两个月，如果我再续签J1两年后，我是否能拿新续的J1去办豁免？
-Yes. You can extend your J1 status and do the J-1 waiver any time you want to.
如果可以，我应该用什么理由去办？需要提交什么文件？
我看网站上说，转成F1可用I-20，转成H1B可以用雇主信，转成绿卡可用结婚证。我目前不存在上着三种情况，我该怎么办这个豁免呢？
-If you need to change of your status to F-1, you need to bring the I-20 to China to get the F-1 visa to come back. But if you want to get the H1 or green card, you need to get the J1 waiver first.
For the J-1 waiver, check this Chinese Embassy website for the details:
