background check = security check? xiaoha2007-08-28 20:54:12

I got a email on my 485 case today after I called about 1+ month ago:

"...The processing of your case has been delayed. A check of our records
establishes that your case is not yet ready for decision, as the required
investigation into your background remains open. ..."

what's background check? is it the same as security check from FBI? do they do it here or oversea? thanks a lot!

大概,可能,应该一样吧.

回复：background check = security check?

is NC the same thing too?

对的.
