回复：对不起我太笨,AP的时间就是签证官给写在AP上的时间对吗?谢谢!

Look at your AP paper carefully and you will find the expiration date on it. This AP expiration date was determined by USCIS officer who approved your AP when you filed the I-131, not decided by the immigration officer at the port of entry when you came back to US from China.
