I am a US citizen and have applied for my mother's I130/I485 concurrent. She did her biometrics in January when she was in the US.
More than 6 months had passed since the application so I called in to ask for status and the USCIS asked her to reappear for biometrics. She is currently outside the US and will not be able to make it for the appointment.
Has anyone been in a similar situation? I am planning to reschedule the appointment. Can I ask for a specific time period? How long can I delay the biometrics.
