回复：8老师，我可以用原先的H1 approval notice 入境吗？

怕我的帖子沉了，你看不到，就提上来问一下。
我怕连premium processing 也来不及。-Just do premium processing, and then ask your employer/lawyer to mail it to you in China. 

另外，premium processing approve 以后，我employer 就是新公司了，那visa 上还是旧公司的名字。我能拿着旧公司的visa 和新公司的797入境吗？
-I don't think it will work because your old employer does not exist anymore and thus, the old H-1 approval notice is invalid. But the visa is valid, so you can use the visa with any valid H-1 approval notice to reenter US.

是不是还要重新签证呢？-No.
