USCIS processing snapshot: Form I-129, Petition for Nonimmigrant Worker. U.S. Citizenship and Immigration Services publishes adjudication-time data monthly for each service center and field office handling I-129. This snapshot covers 4 offices and was last refreshed in March 2026. The average minimum processing time across reporting offices is roughly 3.4 months, with the fastest office currently at 3 months (California Service Center) and the slowest at 4 months (Nebraska Service Center). USCIS processing time is the agency’s own reported window for cases currently receiving decisions, not a guarantee, individual cases can finish inside, at, or beyond the range depending on case complexity, RFE activity, and office workload.

Where I-129 is moving fastest and slowest. Of the 4 offices with reported ranges, 4 are adjudicating I-129 in six months or less while 0 are taking more than a year at the minimum end of their range. That spread matters because USCIS jurisdiction is generally determined by the applicant’s address or the employer’s worksite, so filers cannot freely pick the fastest office, but knowing the range helps applicants set expectations and decide whether to pursue premium processing (Form I-907) where eligible, file a service request on a case that exceeds the stated window, or plan downstream steps such as consular interviews and travel.

How to read the range. USCIS expresses each I-129 range as a two-number window, the lower bound is the time at which 50% of cases are decided and the upper bound is the time at which 93% of cases are decided. The “receipts being processed” column shows the actual filing dates USCIS is currently working on, which is a complementary ground-truth signal: if your receipt date falls within that window, your case is likely at or near the front of the queue. For H-1B employers filing I-129, these agency timelines layer on top of DOL LCA certification and, for workers outside the U.S., State Department consular interview waits, plan the full chain, not just one segment.
