US Immigration Processing Time Estimator
USCIS forms • Nigerian applicants • April 2026 data • Completion date calculator
Select the form you filed. Your form number appears on your receipt notice (Form I-797C).
This is the “receipt date” printed on your I-797C Notice of Action, not the date you mailed or submitted. For online filings, it is usually the submission date.

How the USCIS Processing Time Estimator Works
This tool compares your filing date against USCIS-published median and maximum processing times for each form type (as of April 2026). It calculates how many days have elapsed since USCIS received your application, estimates your completion window, and flags whether your case is still within normal range or has exceeded it.
Days elapsed = Today’s date minus USCIS receipt date
Median completion date = Receipt date + median processing months
Max completion date = Receipt date + max processing months (93% of cases)
Progress percentage = Days elapsed / (Max processing days) × 100
Inquiry eligible = Today’s date is later than the inquiry date published by USCIS for that form
USCIS Processing Times for Key Forms: April 2026 Reference
USCIS publishes official processing times on egov.uscis.gov, updated weekly. These times represent the range within which 80% to 93% of cases are completed. They are not guarantees. Individual cases can fall inside or outside these ranges for various reasons.

Why Processing Times Matter for Nigerian Applicants Specifically
For Nigerian immigrants, processing time is not just a waiting game. It directly affects work authorisation (I-765), travel back to Nigeria (I-131 advance parole), ability to change jobs, and the OPT/H-1B bridge window. A delayed I-765 means you cannot legally work. A delayed I-131 means you cannot visit family in Nigeria without risking your pending green card application.
The 2026 context also includes the partial suspension of new visa issuance to Nigerian nationals for B-1/B-2, F, M, and J categories under Proclamation 10998. For Nigerians already in the US working on I-485 or other adjustment of status cases, this suspension does not directly affect their pending cases, but it does affect family members who may need visas to travel.
What Causes Processing Time Variation
Several documented factors influence how long USCIS takes with any specific case. The service center handling the file matters: Texas, Nebraska, California, Vermont, and the National Benefits Center all have different backlogs. The time of year matters: spring is peak season for OPT and H-1B filings, slowing those categories. Whether your case requires a biometric appointment adds 4 to 8 weeks. An RFE adds 3 to 6 months. Administrative processing (security checks) can add months with no fixed timeline.
The current administration’s backlog of over 11 million pending cases as of early 2026 means overall processing times remain elevated. Naturalization (N-400) has historically improved under the current administration, with times near their lowest since 2016. Employment-based I-485 cases have generally improved as more visa numbers became available. Family-based I-130 cases remain among the slowest.
Realistic Scenarios for Nigerian Immigrants
Scenario 1: H-1B worker filing for EB-3 green card (I-140 then I-485)
Tunde’s employer files his PERM in March 2026. DOL processing: 15 to 16 months (filing date: Q2 2026, expected completion: Q4 2027). Employer then files I-140. EB-3 Rest of World: priority date currently June 2024 or later, so Tunde’s new priority date is likely current, allowing concurrent I-485 filing after I-140. I-140 standard: 8 to 14 months. I-485: 8 to 18 months. Total estimated timeline from PERM start to green card: 3 to 5 years.
Scenario 2: Nigerian spouse of US citizen filing I-130 and I-485
Adaeze marries a US citizen in Lagos in 2025. Her husband files I-130 from the US. Processing for immediate relative I-130: approximately 14.5 months (median). She can file concurrently in the US if she is already legally present, reducing total wait. If concurrently filed, I-485 processing adds 8 to 18 months. If processed via consular route in Nigeria, NVC processing plus Lagos Embassy interview adds 6 to 12 additional months. Total range: 18 to 36 months depending on path.
Scenario 3: Long-term Nigerian green card holder filing N-400 naturalization
Emeka has had his green card for 5 years and files N-400 in January 2026. Processing: median 5.5 months, max around 14 months nationally. However, as of early 2026, naturalization interviews and oath ceremonies are paused for nationals of 39 designated countries. Nigeria is included in this pause. He should monitor official USCIS announcements before relying on any timeline estimate for this form specifically.
Assumptions Used in This Estimator
- Processing time data sourced from published USCIS times as of March to April 2026
- Median times represent the 50th percentile of completed cases over the past 6 months
- Max times represent approximately the 93rd percentile of completed cases
- Times vary by service center; this tool uses national averages across all centers
- RFE scenarios add 3 to 6 months beyond the standard processing window
- Premium processing times (15 business days or 45 business days) apply only when USCIS receives the petition with the premium fee
- PERM processing is handled by the Department of Labor (DOL), not USCIS; times reflect DOL published data
- This tool does not account for visa bulletin wait times for employment-based categories, which add separately to the I-485 timeline
