8/1 H1B Shanghai pass

First of all, sorry for only having English input.

I had my PhD in Mechanical Engineering in US and then joined a Financial Service company. This is the 1st time I came back to China after my status changed to H1B in US in Oct. 2014.

I scheduled for 8am session for visa interview on 8/1/2017. I arrived about 7:15. There was a queue there already. Followed the instructions, moving one step by one step. For H1B, besides one photo, the original copy of I797-A was reviewed by a staff prior to the visa interview. Then I met the visa officer. He asked me about my annual salary and my education background. Then I passed without check. The whole talking time is less than 5 minutes.
