Nonimmigrant Admission Processing Time: How Long Does I-94 Take?

At an average of 30 days (about 1 month), I-94 adjudication moves quickly by USCIS standards. Most applicants receive a decision within a single fiscal quarter, and premium-processing variants — where available — can compress that further. A turnaround under 60 days usually means the form requires limited supporting documentation and the underlying eligibility check is largely automated.

Temporary admissions including tourists, students, business visitors, and temporary workers entering the United States. The official adjudicator is U.S. Citizenship and Immigration Services (USCIS). Status updates and receipt-number lookups are available on the USCIS case status portal.

Among the 8 USCIS form types tracked here, I-94 ranks #1 for processing speed (1 = fastest). The fastest tracked form is I-94 at 30 days; the slowest is I-589 at 730 days — a spread of 700 days, or more than 23 months of difference between the easiest and hardest paths through USCIS.

I-94's 94% approval rate runs 21 percentage points above the cross-form average of 73% across the categories tracked here — a meaningful tilt toward approval. I-94 carries a 94% approval rate, putting it among the highest-approval USCIS form types. A rate this high signals well-defined eligibility criteria and limited discretionary review — most denials trace to incomplete filings or missing evidence rather than substantive ineligibility. Applicants who file a complete package with the correct fee and supporting documents are very likely to receive an approval.

Filing volume for I-94 has been increasing in recent USCIS reporting periods. Rising receipts without a matching rise in adjudicator capacity is the single most common cause of growing backlogs — and is the dynamic the agency cites most often when explaining processing-time slippage in its quarterly performance reports.

USCIS publishes form-type performance data quarterly. The current dataset reflects fiscal year 2023 adjudication, covering 2.1M total applications across 198 countries and 63 field offices. The agency-wide average approval rate across all tracked forms is 82%, which is the benchmark used for the comparisons on this page.

I-94's approval rate is high enough that a complete, on-time filing with correct supporting documents is the dominant factor. Applicants should focus first on ensuring every required exhibit is included and every signature is correct — clerical issues are a leading cause of denials and Requests for Evidence (RFEs) even in high-approval categories. With turnaround under two months on average, applicants can plan around the USCIS-published processing window with reasonable confidence.

Applicants and employer sponsors should also monitor policy changes from USCIS and, where relevant, the U.S. Department of Labor and the U.S. Department of State. Each agency owns a different stage of the immigration pipeline, and a delay at one — for example, a stalled labor certification at DOL — can cascade into the others. The Department of Homeland Security publishes the annual Yearbook of Immigration Statistics, which provides historical baselines this dataset cross-checks against.
