USCIS Processing Times Update June 2026: N-400 Naturalization Delays Explained

As of June 2026, USCIS continues to process Form N-400, the Application for Naturalization, with processing times that differ considerably depending on the applicant's local field office. For EB-3 green card holders who have met the five-year residency requirement, understanding these timelines is essential for planning their path to U.S. citizenship. Processing times vary widely across USCIS field offices, meaning that two applicants filing on the same date could receive their naturalization interview and decision months apart. This geographic variability has been a consistent challenge for applicants and immigration attorneys alike, underscoring the importance of checking the specific field office's current workload before filing. To minimize delays, USCIS and immigration practitioners recommend filing the N-400 as early as eligibility allows — typically 90 days before the five-year (or three-year for spousal) anniversary of receiving permanent residence. Submitting a complete and accurate application with all supporting documentation significantly reduces the risk of Requests for Evidence (RFEs) or administrative holds. For EB-3 applicants who have recently received their green card, the N-400 represents the final milestone in the U.S. immigration journey. Staying informed about current USCIS processing time trends helps applicants set realistic expectations and plan life decisions — such as international travel or employment changes — accordingly. Applicants are encouraged to monitor the official USCIS processing times tool regularly and consult an immigration attorney if their case exceeds the posted processing window, as an inquiry or service request may be warranted.
