Filed I751 in September 2021 , transfered to Nebraska Service Center ( LIN ) , after biometrics reuse no update. Then filed N400 in September 2022 received same day biometrics used and on November 2nd case updated as interview scheduled you will get a notice for that. Got notice only for N400 . And interview scheduled for December 13 at my area service center . Went with my spouse officer called my spouse first for interview then I realized i have two interviews , one for I 751 and another for N400, as for N400 you don't have spouse interview. All went well. Both interviews passed . But officer told me since I have two year extension letter which is good for another one year. So they are not printing my new GC . He assured the interview will be soon. Fingers Crossed waiting for interview notice . Thanks everyone for your help.
