The RFE you received should indicate the address to which the Form G-325A and medical examination should be mailed. You need to mail all requested documents at the same time. You should receive a biometrics appointment notice shortly after submitting the RFE response. Contact USCIS by phone if you do not receive a biometrics appointment notice within 30 days.
