answer
the documents that the officer request:
receipt notice of EAD, receipt notice of I485, filled form I765 (ead application, need to sign before him), passport
I also took a check but he didn\'t ask me to pay, I took company letter, payroll, he didn\'t ask for them.
I think he asked my parent\'s name just for verification. He also verified my address, because my current address is different those I wrote in the forms, I direct all those mail to my friend\'s house which is much safer than my downtown san jose place.
I applied ead 7/24 (RD of I765), so today is the 91th day.
the officer is not polite, I asked him what\'s my status of I485, because I think he got my parent\'s name through the I485 information. But he only told me it is still pending.
