My wife and I had our combo I-751 and N-400 interview today with similar outcome. Her paper stated that she passed the N-400 exams but a decision cannot be made yet. The office told us that since her biometrics were taken so long ago, they will have to re-run them and then a decision will be made for the I-751. Does anyone know how long this process will take and how soon we’ll know an answer for both?
