Processing time varies by case

USCIS processing time depends on the form, the category you filed under, the office or service center handling it, and the specific facts of your case — and it changes over time. MyCases does not publish averaged processing-day or approval-rate estimates across cases.

Purpose and process
Typical requirements: 5 years as an LPR (3 years for marriage-based), residency and physical-presence rules, English and civics tests, and a good-moral-character review. Process: filing → biometrics → interview + test → oath ceremony.
Who files it
Lawful permanent residents who meet the residency and moral-character requirements.
Common USCIS statuses for this form
Case Was Received
USCIS has accepted delivery of your filing, logged it, and generated a receipt number beginning with a three-letter service center code. The status confirms that your package and fee were received; it does not mean an officer has read a single page. It also fixes two things that matter later: the received date (which is normally your priority date in preference categories) and the office responsible for the case.
Biometrics Appointment Was Scheduled
USCIS has scheduled your biometrics appointment and mailed an I-797C notice with the date, time and assigned Application Support Center. Biometrics captures fingerprints, a photograph and a signature so identity and background checks can be completed. It is a procedural step, not a challenge to your evidence.
Interview Was Scheduled
USCIS has scheduled an interview and mailed a written notice giving the date, time, location and the documents you must bring. Note carefully that the day this status appears is not the interview date; always rely on the printed notice.
Case Was Approved
USCIS approved the application. This is a decision status and the outcome is favorable, but approval is not the same as having the document in hand: most categories still go through card production, notice mailing, or transfer to another agency, each with its own status. The legally operative item is the written I-797 approval notice that follows; the online status is only a signal that it is coming.
Case Was Denied
USCIS issued a denial. The written notice sets out the legal and factual grounds, and it is the only reliable basis for deciding what to do next; never infer the reason from the one-line online status. A denial does not necessarily end the road either, since appeals, motions to reopen or reconsider, and refiling may be available depending on the category.
Frequently asked questions
How long after the N-400 interview until the oath?
If you pass and same-day oath is available, it happens that day. Otherwise, the notice usually arrives within 1–3 months.
How long is N-400 processing right now?
The national average is roughly 8–12 months but varies by field office. Los Angeles, New York and San Francisco tend to be slower.
Do I get denied immediately if I fail the interview?
Not necessarily. Officers may give a second chance to retake the English or civics portion. Formal denial only follows a genuine eligibility issue.
