US Visa Approval Odds Calculator
Nigerian applicants • Based on 2025 USCIS approval data • Profile-adjusted estimates
Select the specific category you are filing. Each has a different baseline approval rate from USCIS data.
Attorney representation is associated with meaningfully higher approval rates across most categories, particularly for complex self-petition cases.
An RFE lowers odds somewhat but most cases with strong responses are still approved. A prior denial is more significant and requires genuinely new evidence.
Prior immigration violations are grounds for inadmissibility and can result in denial even for otherwise strong cases.

How the Approval Odds Calculator Works
This calculator starts with the official USCIS approval rate for your specific visa category, sourced from published USCIS quarterly and annual data (FY2025, through Q4). It then applies directional adjustments based on documented factors that research shows are associated with approval or denial patterns.
Adjusted odds = Baseline approval rate + Evidence quality adjustment + Attorney representation adjustment + RFE/denial adjustment + Immigration history adjustment
Each adjustment is capped so the final result cannot exceed 97% (no application is ever a certainty) or fall below 5% (all categories retain some possibility of approval with the right circumstances). The adjustments are directional indicators, not statistical probabilities.
USCIS Approval Rates by Category: What the 2025 Data Shows
USCIS publishes quarterly and annual adjudication statistics at uscis.gov. These numbers show what percentage of completed cases were approved in a given period. They include all applicants, from the weakest to the strongest cases.
| Category | FY2025 Approval Rate | Trend | Key Factor |
|---|---|---|---|
| H-1B (petition) | 97.8% | Stable, rising | Employer petitions; specialty occupation scrutiny |
| O-1A/O-1B | ~93.8% | Stable | Evidence quality; RFE rate declining (18.7% in 2025) |
| L-1A/L-1B | ~92.8% | Improving | Qualifying manager/executive role documentation |
| EB-1A (extraordinary ability) | ~66.9% (FY25 full year) | Declining | Stricter final merits review; evidence quality critical |
| EB-1B/EB-1C | ~96%+ | Stable | Strong employer support; employer petition |
| EB-2 NIW | ~54–67% (varies by quarter) | Volatile; recovering from FY24 low | Highly dependent on petition quality |
| EB-2/EB-3 (PERM) | ~85.8% | Slightly declining | PERM accuracy; employer sponsorship quality |
| I-485 (employment) | ~90% | Stable | Underlying I-140 approval; inadmissibility grounds |
| I-485 (family) | ~90% | Stable | Sponsor income; relationship evidence; prior violations |
| N-400 Naturalization | ~96% | Stable | Meeting eligibility; civic knowledge test |

Why the EB-1A and EB-2 NIW Approval Rates Dropped
The most dramatic changes in 2024 and 2025 came in the self-petition categories. EB-2 NIW approval rates dropped from above 90% historically to around 43% in FY2024, before partially recovering to 54 to 67% through FY2025. EB-1A rates dropped to around 53% in Q4 2025.
The primary driver is stricter “final merits” review at USCIS. Officers are now applying a more demanding standard in the second stage of review, even when applicants technically satisfy the criteria count. Cases with quantifiable, independently verified impact are still being approved at good rates. Cases with vague claims or thin documentation are being denied or RFEd at much higher rates than before 2024.
Factors That Affect Approval Odds Across All Categories
Evidence Quality
For self-petition categories (EB-1A, EB-2 NIW, O-1), evidence quality is the single most important factor. Strong cases document: peer-reviewed publications with citations, awards from recognized organizations, media coverage in major publications, high salary compared to peers, expert letters from independent experts (not just colleagues or supervisors), and evidence of the applicant’s work being used or adopted by others.
Attorney Representation
Statistically, attorney-represented cases in complex categories (EB-1A, EB-2 NIW) have meaningfully higher approval rates than pro se (self-filed) cases. For straightforward employer-petition cases like H-1B, the difference is smaller since the employer’s attorney typically handles it. For self-petitions, a qualified immigration attorney who specializes in that specific visa category makes a substantial difference in petition structure and evidence framing.
Prior Immigration Record
Prior immigration violations are grounds for inadmissibility under INA Section 212(a). This includes prior overstays, deportations, entries without inspection, and misrepresentation on prior applications. These do not automatically disqualify a petition, but they significantly reduce approval odds and often require separate inadmissibility waiver filings.
Realistic Scenarios for Nigerian Applicants
Scenario 1: Software engineer filing H-1B via employer
Tunde is an engineer at a US tech company. His employer files an H-1B petition for a Level III salary role with a proper specialty occupation description. The employer uses a corporate immigration attorney. Clean immigration history. Baseline H-1B approval rate: 97.8%. With strong employer documentation and attorney representation, his adjusted estimate sits at 95 to 97%. The main risk is an RFE on specialty occupation if his degree is not directly related to the role. Well-documented degree-to-job alignment reduces that risk significantly.
Scenario 2: Academic researcher self-petitioning EB-1A
Dr. Adaeze is a published biomedical researcher with 40+ citations, two best-paper awards from international conferences, and a letter from her department head. She has no US immigration violations. She hires an experienced EB-1A attorney. Baseline EB-1A rate: approximately 67%. With strong evidence (3+ strong criteria clearly met) and attorney representation, her adjusted estimate is around 78 to 82%. If she only marginally meets 3 criteria with thin evidence, the estimate drops to 45 to 55%.
Scenario 3: Green card holder sponsoring spouse for I-130
Emeka is a US green card holder filing I-130 for his wife in Nigeria. This is an F2A family preference category with a visa number backlog. The I-130 itself has a reasonable approval rate (~90%) but the total wait includes the preference category queue. A prior short overstay by his wife on a previous visit slightly lowers odds. Clean relationship documentation and financial capacity of sponsor are the key factors for the I-130 itself.
Assumptions Used
- Baseline rates sourced from USCIS FY2025 quarterly adjudication statistics (approved and denied completed cases)
- Pending cases are excluded from baseline rate calculation (following USCIS methodology)
- Adjustments are directional (+/- percentage points) based on documented research patterns, not statistical regression
- Attorney representation adjustment reflects research showing higher approval rates for represented EB-1A/NIW cases
- RFE adjustment reflects the documented 3 to 6 month processing impact and historically lower final approval rates for RFE cases versus clean filings
- Immigration history adjustment reflects INA 212(a) inadmissibility grounds and their documented impact on denial rates
- Maximum adjusted odds: 97% (no application is a certainty)
- Minimum adjusted odds: 5% (even challenging cases retain some possibility)
