The U.S. Citizenship and Immigration Services (USCIS) recently released naturalization processing statistics for every USCIS local office in the United States. The report includes statistics from fiscal years 2010, 2011 and 2012.
The report includes statistics on the number of applications accepted, approved and denied. Additionally, the report indicated that normal naturalization cases are taking about 4.9 months to process (on average), while military naturalization cases are taking about 4.2 months.
To ensure your eligibility for naturalization, and to avoid unnecessary N-400 denials, contact a New York N-400 attorney.
The report also provides average processing (or cycle) times for N-400 applications, calculated on a service-wide basis. As of October 2011, the average service-wide processing time for N-400 application was 4.2 months for military N-400 case and 4.9 months for non-military N-400 case.
Please note that these average processing times are calculated on a service-wide basis, taking into account all field offices (including ones with very little load). A more reliable (and accurate) way to obtain specific field office processing times is to check the field office processing times for N-400 cases on USCIS website.
