Citizenship

Hi guys. My husband had his interview for n400 last week on Tuesday. He was recommended for approval and the io told him he will get his oath ceremony in 30-60 days. She told him it will be in the same building and to bring his two resident cards and his passport. His paper has 3 things checked. “ you passed....etc Uscis will send u a decision in the mail......etc. and last “ Congratulations you are recommended for approval””””””. Only problem is we have no updated status online. All it says is “ we scheduled your interview” it has been 8 days since his interview. Can anyone relate to not getting an updated status??? I feel like maybe it will update when they actually schedule the interview. We never got an in line for interview when we were waiting for his interview. It went from we reviewed ur biometrics to “we scheduled ur interview “ is this normal???? Field office is New Orleans.
