I am at the fingerprinting stage and have my appointment for biometrics. Unfortunately, due to unforeseen circumstances I am unable to go through the N-400 process at this time. Do I just not show up at the biometrics appointment and abandon the application or withdraw it by writing to the USCIS, if the latter what is the procedure? do I fill out a form or just write to them at the address provided on the biometrics notice? Any help would be appreciated. Thanks.
