Update..
My pending I-751 was approved on 1/23 followed by approval of N-400 and oath ceremony schedule on 1/24. The oath ceremony is scheduled for 2/14 during which I will be travelling abroad. I Will go ahead and return the Oath ceremony appointment notice to Seattle office along with a letter explains the reason I won’t be attending the ceremony. I expect another appointment within 6 weeks.
Good luck everyone!
