回複：Yes,you need to apply a H1 visa for return to USA

Hello Xiao Bai-Bu, deeply thanks.

However sorry to ask your more questions.

1) You mean that once I am back to China, my current H1 visa is invlid?

2) If I back to China, where I apply H1 VISA, at one of USA embassies in China in Person? whether I need new offer letter from Current employer before I leave? How long will it to get new H1 approval?

Much Thanks
