回複：回複：回複：請教皮老師和8老師，要去一所學校做博士後，還沒有開始。現在要回國辦理H1B。同時拿到另外一個學校的博士後。

But you need to work for the first school to get a paycheck for the h1 transfer to the second school. Another choice is that you may ask the second school to file the H1 petition now and use premium processing to get it approved in 15 days. Then, you just use the new H1 approval notice and the job offer letter to apply for the h1 visa in China so that you can just ignore the first H1 approval notice and not need to do the h1 transfer after you return to US from China.
