NBC Lee’s Summit, MO 64002: Processing Times and Delays

Cases handled at the USCIS National Benefits Center in Lee’s Summit, Missouri don’t have a single published processing time, because the NBC is a pre-processing hub for more than 30 form types and most cases are decided later at a local field office. To estimate your wait, you check the USCIS processing times tool by form and by the office that will actually decide your case, then use that same tool to see whether you’ve passed the point where you can submit an inquiry. This guide walks through how NBC Lee’s Summit processing times work, why yours may be running long, and the specific escalation steps available when it is.

Why There’s No Single NBC Processing Time

The National Benefits Center operates under U.S. Citizenship and Immigration Services as a centralized pre-processing hub.¹ For most high-volume forms, it isn’t where the final decision happens. Staff there create your case record, generate your receipt number, verify fees and form editions, review supporting documents, coordinate FBI fingerprint and name checks, and schedule biometrics at an Application Support Center.² When background checks clear and the file looks complete, the NBC decides where to route your case for adjudication.

Some forms the NBC decides itself. Form I-765 employment authorization and Form I-131 advance parole filed with a Form I-485 are adjudicated at the NBC. Form I-130 petitions for a foreign relative may be both pre-processed and decided there. International adoption petitions (Forms I-600, I-600A, I-800, I-800A) are handled at the NBC’s Overland Park sub-office.³

Others just pass through. Form I-485 adjustment of status and Form N-400 naturalization are pre-processed at the NBC and then sent to your local field office for the interview and decision. That distinction is the whole reason you can’t rely on one number: the time your file spends in Lee’s Summit is only part of the total wait.

How to Check Your Processing Time

Go to the USCIS processing times page, then select your form, your category, and the office handling your case. The estimate shown is how long USCIS took to complete 80% of adjudicated cases of that type over the most recent six-month period.⁴

Here’s the rule that trips people up. If your case is a family-based or employment-based I-485, an N-400, or an N-600, and the listed office is the National Benefits Center, USCIS tells you to check the processing time for your local field office instead.⁴ The NBC pre-processes those forms, but your field office decides them, and its workload sets your actual wait. Checking only the NBC time gives you the wrong picture.

The same tool also tells you whether your case is late. Enter your receipt date, and the system calculates a case inquiry date based on the time it takes to complete 93% of cases. If that date is still in the future, you’re within normal processing times and USCIS won’t take an inquiry. If the date has passed, the tool gives you a link to submit one.⁴

Reading Your Receipt Number

After USCIS accepts your filing, you receive a Form I-797C Notice of Action with a 13-character receipt number: three letters followed by ten digits.⁵ The three-letter prefix tells you which facility has your case. MSC and NBC prefixes mean the National Benefits Center. LIN is the Nebraska Service Center, SRC is the Texas Service Center, and IOE indicates a case filed electronically.

Enter that receipt number into Case Status Online to see the most recent action on your file.⁶ Updates might show receipt, biometrics scheduling, a request for evidence, or transfer to a field office. The tool confirms movement; it won’t predict the next step.

What’s Slowing Your Case Down

Requests for Evidence

If USCIS accepts your filing but finds the evidence incomplete, outdated, or insufficient, the NBC may issue a Request for Evidence.⁷ Common triggers are missing birth or marriage certificates, expired medical exams, foreign-language documents without certified English translations, and insufficient proof of a qualifying relationship for family petitions. An RFE pauses your case until you respond, and the response deadline is firm.

Background Checks

The FBI name check is the step you have the least control over. USCIS runs it for every naturalization applicant and many adjustment filers.² Most clear within weeks. If your name matches or resembles a name in FBI databases, resolution can take months.

Biometrics

I-485 and N-400 applicants must give new biometrics in person at an Application Support Center. Neither form qualifies for biometrics reuse, even if you provided fingerprints recently for another application.⁸ Missing your appointment forces a reschedule on top of whatever backlog the ASC already has.⁹

Rejection at Filing

An application submitted without a valid signature or the correct fee is rejected outright and sent back, which is worse than an RFE because the clock never starts.⁷ You refile from scratch, pay again, and wait for a new receipt number.

Volume and Policy

Some delays sit outside your file entirely. High submission volumes in certain fiscal quarters create backlogs at the NBC and at field offices. Policy changes redirect resources toward particular case types, which slows the rest. DHS staffing levels shift, and those shifts move through the system.

What to Do When Your Case Is Past Normal Times

Submit an e-Request

Once the processing times tool shows your case has exceeded normal limits, submit an e-Request through the USCIS website.¹⁰ You need your receipt number. Save the date you submitted it, because later escalation options require showing you gave USCIS a chance to respond.

Call the USCIS Contact Center

The USCIS Contact Center is 800-375-5283. The speech-enabled system routes you to self-service first and may not connect you to a live representative if it decides an online tool can answer you.¹¹ Tier 1 handles general status and rescheduling. More complex issues can be escalated to Tier 2 Immigration Service Officers. Calling is most useful when you’ve already used the online tools and have a specific question.

Request Help from the CIS Ombudsman

If your e-Request doesn’t resolve things, the CIS Ombudsman at the Department of Homeland Security can step in, but only after you clear specific hurdles. You must have contacted USCIS within the last 90 days and given the agency at least 60 days to address the problem. Your case inquiry date on the processing times tool must have already passed. And USCIS must not already have approved an expedite request on your case. If no published processing time exists for your form type, you must have waited at least six months since filing.¹²

Congressional Inquiry

Your U.S. senator or representative can also make an inquiry. Congressional offices have dedicated liaisons at USCIS field offices, and requests sent through the Congressional Web Portal get an immediate initial acknowledgment. You’ll need to sign a privacy release addressed to USCIS with your full name, date of birth, and receipt number. Don’t include your Social Security number on that form. This route works best for cases that have genuinely stalled, not ones still within the posted window.

Requesting Expedited Processing

USCIS lets you ask to move ahead of the queue, but approval is discretionary and requires documented urgency. The main grounds are severe financial loss and emergency humanitarian situations.¹³

For severe financial loss, a company needs to show it’s at risk of failing, losing a critical contract, or laying off employees. For an individual, evidence of job loss may suffice, but needing an employment authorization document by itself does not qualify. USCIS expects the urgency to come from circumstances beyond your control, not from filing late or ignoring an RFE.

Humanitarian expedites cover serious illness, disability, death of a family member, or extreme conditions caused by natural disasters or armed conflict. Filing a humanitarian-based application like asylum does not on its own justify expedited treatment unless additional time-sensitive factors exist.¹³

Urgent travel can also qualify, with specific documentation: a death certificate or obituary for bereavement, a doctor’s letter for medical travel, or an employer letter on company letterhead for a work commitment. Generic statements of urgency without supporting documents almost never succeed.

Filing Mistakes That Cost You the Most Time

The delays that hurt most are the preventable ones. Before you mail anything, run through these:

Verify the current fee for your specific form on the USCIS fee schedule immediately before filing. Fees change.
Sign the form. An unsigned application is rejected, not queued. If both spouses’ signatures are required, both must be present.
Use the current form edition. Check the edition date in the bottom-left corner against the form page on uscis.gov.
Include certified English translations for every foreign-language civil document. The Form I-693 medical exam is generally valid for two years from the civil surgeon’s signature, and submitting an expired one guarantees an RFE.
Keep a complete copy of everything you send. If USCIS issues an RFE, you need to know exactly what you already submitted.

Getting the application right the first time is the single most effective way to keep your wait short. Every rejection and every RFE adds weeks or months that no amount of follow-up calls can recover.
