Xiaobaitu, sorry to trouble you too much

I just found that in the 485 RFE the INS officer required that "complete the item(s) that are checked or circled on the attached applications or forms".

The officer attached a copy of part3 of the original I-485 form on which the items "your mother's first name" and "your father's first name" were checked.

In the original form, I did fill in my parents' (who have never entered the US) first names correctly, and I don't understand why these area were checked. The officer required the same thing in my wife 485 RFE.

Could you please advise on this?

Also I found that my entering visa (I-20, F1) bears an INS stamp, but my dependents' entering visa (I-20, F2) did not bear the stamp, although my dependents' passports and I-94 cards do bear INS stamps. Was anything carelessly negelected on my dependents' entering visa by the INS officer at the port? In this case, can I still copies of my dependents's entering visa to answer the question "you indicated that you were not inspected by the INS officer, please explain?"?

I am sorry troubling you too much.

Thank you!
