How long does it take to hear from USCIS after interview?

Theoretically, you must get a response from the USCIS about your naturalization application within 120 days after your interview. Within 30 days following your interview, the USCIS is required to give you an official communication of their decision about your green card application.

Following the applicant’s interview, it is typical for United States Citizenship and Immigration Services (“USCIS”) to take some time before issuing a formal decision in a naturalization case. USCIS has 120 days under the law to make a determination.
