oath taking wrong address

[em-em 0]

I applied N600 for my son last July 2016 and received a NOA Aug 2016. that was the first and last letter I received from them until I decided to write them a letter this February 2018 after numerous times of calling them and doing online inquiry. Finally, they updated the case status online to scheduled ceremony. The problem was I didn't receive the letter. Thus, I called USCIS and thankfully, talked to an officer. That's when I found out that they sent the letter to Oak Harbor WA. it was the wrong address since we are staying overseas here in Japan since my husband is member of the military. The officer then told me to change my address. I did the AR-11 online but just put our old address here also in Japan just another base. and put our current address as my new address. The oath ceremony will be held in Oak Harbor this coming April 18. We cannot go to Oak Harbor for the ceremony especially I didn't recieve the letter they mailed. I'm still waiting for their reply but still worried that they might say we neglected the oath taking. even if I already sent them another mail 2 weeks ago explaining that we never moved and still use the same mailing address they used in sending the I-797C. up till now, I never heard anything from them.  thank you for your help
