USCIS Service Center Speed Heatmap | Visafig Official Figures
Two applicants file the same form on the same day and wait wildly different times — often because their cases landed at different service centers. This uscis service center heatmap puts the typical processing months for I-485, I-140, I-130, N-400, I-765, and I-129 side by side across Texas, Nebraska, California, and Vermont, color-coded from fast to slow. It won't tell you which center your case will hit — USCIS assigns that — but it shows where the bottlenecks tend to sit so you can plan the wait realistically.

|---|---|---|---|---|

| I-140 (Petition) | 4–9 mo | 2–7 mo | 7–12 mo | 5–10 mo |
| I-130 (Family) | 10–16 mo | 8–14 mo | 13–19 mo | 11–17 mo |
| N-400 (Naturalization) | 4–8 mo | 2–6 mo | 7–11 mo | 5–9 mo |
| I-765 (EAD) | 3–8 mo | 1–6 mo | 6–11 mo | 4–9 mo |
| I-129 (H-1B) | 2–6 mo | 1–4 mo | 5–9 mo | 3–7 mo |
Green = faster typical processing, red = slower. Cells show the typical month range for each form at each center, derived from USCIS_TYPICAL_MONTHS plus a local per-center offset (educational estimate). Real per-center times vary by workload and must be confirmed on the official USCIS processing-times tool.
Frequently Asked Questions
What are the USCIS service centers?
USCIS routes paper and electronic filings to four main centers — Texas (TSC), Nebraska (NSC), California (CSC), and Vermont (VSC) — plus specialized lockboxes. Each center handles a mix of forms, and your receipt number's prefix (e.g., LIN, SRC, WAC, EAC) tells you where the case landed.
Why do processing times differ by center?
Centers absorb different case volumes and form mixes. When one center is overloaded, USCIS shifts workloads between centers, so a form that is fast at Nebraska may sit longer at California in a given period. Backlogs are workload-driven, not geographic.
Is California really slower?
California often shows longer typical times for high-volume forms like I-485 because of its caseload, but the gap is not fixed. The heatmap's California offset is an educational estimate; the live USCIS tool is the only authoritative source for the current month.
Can my case be transferred between centers?
Yes. USCIS routinely moves pending cases between centers to balance workload. A transfer changes where your file is worked but not the underlying eligibility or the law applied to your case.
How do I check which center has my case?
Your I-797 receipt notice shows a receipt number whose first three letters map to a center (LIN = Nebraska, SRC = Texas, WAC = California, EAC = Vermont). Enter that number in the USCIS case-status tool to track it.
Does I-485 use the same centers as I-130?
They can land at different centers depending on filing method and workload. An I-130 filed online, for example, may be adjudicated separately from a concurrent I-485, which is why the heatmap lists them as distinct rows.
Which center handles N-400?
Naturalization (N-400) is often handled at field offices rather than the four mail centers, but the underlying interview-scheduling backlog still varies by location. The heatmap shows typical months as a planning reference only.
Does premium processing change the center?
Premium processing (for eligible forms like I-140 and some I-129) sets a 15-calendar-day clock regardless of center, but it is a paid upgrade and not available for I-485 or N-400. It short-circuits the heatmap's typical ranges for those forms.
Does the center affect my approval odds?
No. Approval turns on the facts and the law, not the center. The center only affects how long the wait is. Don't pick a filing strategy to 'land' at a faster center — you usually can't control the assignment.
Any planning tip?
Use the heatmap to set expectations, not to game the system. File correctly the first time, watch the official USCIS processing-times tool for your exact form and center, and consider premium processing where eligible to bypass the typical range.
