I-485 Processing Times 2024–2026: Trends, Data & What to Expect
I was one of the lucky ones — my I-485 was processed in about 3–4 months. But I've seen friends and community members wait well over a year, constantly refreshing the USCIS website and wondering if something is wrong with their case. The truth is, for most people, it's not their case — it's the system. Here's a data-driven look at what's actually been happening with I-485 processing times from mid-2024 through mid-2026.
The Data at a Glance
The chart on this site's Timeline tab tracks the USCIS-published upper bound for I-485 processing at the National Benefits Center (NBC), collected manually on the first of each month. The trend is clear: times increased steadily from 15 months in June 2024 to a peak of 20.5 months in May 2025, then dipped slightly before stabilizing around 20 months through early 2026.
That's a 5-month increase in under a year — which explains why so many people who filed in late 2023 or early 2024 are still waiting.
Why Did Processing Times Increase?
Post-pandemic backlog: USCIS offices reduced capacity significantly during 2020–2021. Cases that stalled during that period continued to accumulate, and by 2024 the system was still working through that backlog. Applications filed in 2022 and 2023 were still being adjudicated well into 2025 and 2026.
Fee-based funding model: USCIS is primarily funded through filing fees rather than congressional appropriations. When application volume drops or fee increases are delayed, hiring slows and adjudication capacity shrinks. The agency proposed a significant fee increase in 2024, but implementation was gradual, meaning staffing didn't immediately catch up to demand.
Field office interview scheduling: Not all I-485 cases are interview-waived. Marriage-based cases and certain employment-based cases require an in-person interview at a local Field Office. Interview slots at many offices are booked 6–12 months out, which adds substantially to the total timeline even after NBC completes its initial review.
Policy and procedure changes: USCIS periodically updates its internal processing guidance — on biometric reuse, interview waiver eligibility, and document requirements — and each change creates temporary slowdowns as officers adapt and systems are updated.
NBC vs. Other Service Centers
The data above applies specifically to the National Benefits Center (NBC), which handles the majority of I-485 filings. NBC is the primary processing hub for employment-based adjustment of status cases. If your receipt number starts with NBC (or the legacy MSC), the data above is most relevant to you.
Other service centers have different timelines. Vermont (EAC/VSC) and Texas (TSC/SRC) handle specific visa categories and have historically shown different patterns. Always check the USCIS official page filtered by your specific service center.
Interview-Waived vs. Interview-Required Cases
This is one of the biggest variables in processing time. NBC has an interview waiver program for certain employment-based I-485 cases. Cases that qualify for a waiver can be approved without ever being transferred to a Field Office, significantly cutting the total timeline. If your case has been at NBC for over a year without being transferred (no BC/BA codes in your event log), there's a reasonable chance you're in the interview-waiver pool.
Marriage-based cases are almost always required to interview at a local Field Office. The NBC completes its initial processing, then transfers the case. The Field Office scheduling backlog is an entirely separate queue with its own wait times.
What to Do If Your Case Is Outside Normal Times
If your case has exceeded the published processing time range, you have a few options. First, submit a case inquiry through your USCIS online account. This is the official channel for asking about delayed cases, and it creates a record of your inquiry. Second, if the delay is significant and affecting your employment authorization or travel plans, consulting an immigration attorney is worthwhile. Attorneys can sometimes identify holds or issues that aren't visible in the public-facing case status. Third, contacting your congressional representative's office for a Congressional Inquiry is an option in extreme cases — some people report movement after this step, though it's not guaranteed.

What Does the Future Look Like?
Based on the available data, I-485 processing times at NBC have stabilized in the 18–20 month range. A significant drop in the near term would require either a reduction in new applications or a meaningful increase in adjudication capacity — neither of which appears imminent based on current trends. The most realistic expectation for someone filing today is a wait of 18–24 months, with considerable variance depending on case type, service center, and whether an interview is required.
Processing times are a snapshot, not a guarantee. Individual cases can move faster or slower than the published ranges for many reasons. The published times represent a median, not a maximum.
