Time Gap Between Spouse's Approval

[Notopic]

Hi all,
I have received the approval notice of I-485. But my husband who was the derivated applicant has not yet received the approval. Do you have any idea about how soon he could get the approval? And usually what's the time gap between spouse's approval? Would it be helpful if I or he call the NSC?
Thank you.

From what I observed on this board and in real life it may be anything between a couple of days and a couple of years, especially if you are unlucky to have your case in the NSC. Sorry, there's no definite answer to your question.

My husband received his on May 10, and I (derivative) received mine 10 days later. Our asylums were approved the same day and we applied for adjustment the same day, but were approved 10 days apart.
