Naturalization Approved but Waiting for Oath Ceremony? How to Overcome USCIS Delays

Are you stuck with your naturalization approved but waiting for an oath ceremony? Learn about the USCIS 120-day rule, attorney warning letters to USCIS, and how a lawsuit can force USCIS to schedule your swearing-in. ​Passing your naturalization interview is an incredible milestone. However, that excitement can quickly turn into frustration when you find yourself with your naturalization approved but waiting months on end for an oath ceremony.

If you have been waiting well over 120 days since your interview and still haven't received your oath ceremony invitation, you are not alone. Many soon-to-be citizens across the country are currently stuck in this administrative limbo due to "security reviews," misplaced files, or processing backlogs. Fortunately, the law is on your side, and you do not have to wait indefinitely.

The USCIS 120-Day Rule Explained
Federal law provides a specific timeframe for U.S. Citizenship and Immigration Services (USCIS) to finalize your citizenship case. According to federal regulations (specifically 8 U.S.C. § 1447(b)), USCIS must make a final determination on your naturalization application within 120 days of your interview.

While you may have been verbally told you passed, or received a notice stating your case was recommended for approval, you are not officially a U.S. citizen until you take the Oath of Allegiance. If 120 days have passed and your delayed oath ceremony with USCIS is still pending, you have the legal right to take action.

Step 1: The Legal Follow-Up Letter to USCIS 
At ImmigraTrust, we usually suggest starting with a firm, targeted approach before jumping straight into federal court. Given that the regulations require USCIS to respond within 120 days, we can draft a formal follow-up letter from our legal team and send it directly to the local USCIS office handling your case. This is not a standard customer service inquiry. The letter explicitly reminds the local office of their legal obligation under the 120-day rule and issues a clear warning: we need a response and a scheduled ceremony date, or we will file a federal lawsuit. In our experience, this strategy is highly effective. Usually, the local office will respond to this letter by immediately pulling your file and scheduling your oath ceremony to avoid the hassle of litigation.

Step 2: Filing a Lawsuit for a Delayed Oath Ceremony
What happens if the local office simply ignores the warning letter? If they do not respond and you still do not get your oath ceremony, we can proceed with a lawsuit in federal court to force them to act. Depending on the exact circumstances of your delay, this may take the form of a Section 1447(b) petition or a Writ of Mandamus.

By filing a lawsuit, we take the power out of USCIS's hands. Once we file a formal complaint in court, the government is legally required to respond within 60 days. The good news for applicants is that this rarely results in a drawn-out court battle. Instead of spending their time and resources litigating the matter before a judge, the government attorney assigned to defend the lawsuit will usually contact USCIS directly to determine why the case is stalled. In most instances, USCIS will provide an update, finalize the case, or schedule your oath ceremony within that 60-day window simply to resolve the lawsuit and close the file.

If they still refuse to act, a federal judge has the legal authority to break the deadlock by either ordering USCIS to immediately schedule your ceremony or by taking jurisdiction and administering the oath of citizenship directly in court.

Don't Let Your Citizenship Stall
A delayed oath ceremony can disrupt your life, complicate international travel plans, and delay your ability to sponsor family members for their own green cards. You have worked too hard to get to this point to let bureaucratic delays hold you back from your American dream.

If you have been waiting over 120 days since your interview, it is time to force an answer.
