回复：请教皮匠, 863211老师: should I withdraw NIW 485?

EB1B 485 was approved at NSC last week. I have another NIW 485 that is still pending at NSC. Should I withdraw this NIW 485 and how?
-You do not have to, but you had better do it just for saving USCIS some time (for courtesy).
Does it has anything negative impact on the approved 485?
-Not at all.

Or I should just leave it there, and NSC will deny it when the Service processes it in future?
-see above answer.
Thanks...
