Analysis / Source data

USCIS source data we use

USCIS publishes data in different formats depending on the form. Below is what each dataset is, what questions it answers, and links to both our consolidated CSVs and the original XLSX files on uscis.gov.

The two families of USCIS data

Everything on EB5 Base comes from public USCIS releases. USCIS publishes data in two broad shapes, and they are not interchangeable — each answers a different kind of question:

Form-specific detail reports

USCIS sometimes publishes a dedicated workbook for a single form family — broken out by country, category, region, or priority date depending on the form.

  • I-485 pending inventory: Monthly employment-based snapshot by preference category, country of chargeability, and priority date year/month. Good for "how long is the queue today?"
  • I-526 / I-526E filings: Quarterly EB-5 receipts disaggregated by country of birth × TEA set-aside category × receipt month. Good for "how many filings came from Vietnam in Q1?"

All Forms throughput reports

Once a quarter USCIS publishes one giant workbook with receipts, approvals, denials, completions, pending inventory, and median processing months for every immigration form — including the EB-5 family.

  • Good for: "How many I-526E petitions did USCIS approve last quarter?" or "What's the current median processing time for I-829?"
  • Not so good for: country-level or TEA-category-level questions — those numbers only appear in the form-specific detail reports above.

Which one should I use? If you care about who is filing (country, TEA category, priority date), start with the form-specific report. If you care about what USCIS is doing (approvals, denials, processing times), use the All Forms throughput report. For a full picture, use both — that's how the I-526 explorer is built.

I-485 pending inventory

Monthly employment-based adjustment-of-status snapshots, Feb 2024 → today.

What this dataset contains

USCIS posts one Excel workbook per month with a count of every employment-based I-485 petition still pending as of that snapshot date. The workbook breaks totals out by: preference category (EB-1 through EB-5 and the carve-outs), country of chargeability, and priority-date year/month bucket. This is the only public source for the size and shape of the green-card queue.

  • Best for: Snapshot of "how long is the line" at a point in time, comparing two months, or tracking a priority-date cohort as it moves through the queue.
  • Limitations: It's a pending inventory, not a flow of new receipts or approvals. It also only covers I-485 (adjustment of status in the USA), not consular processing abroad.

Consolidated CSV

Fine for a single snapshot, awkward for trends: you would otherwise download, open, and stitch 26 files by hand. EB5 Base does that consolidation for you. One CSV with every non-zero cell across all monthly snapshots (country, category, visa status, priority-date year/month, count).

Download i485-pending-inventory.csv

Suppressed USCIS values ("D") appear with an empty count and suppressed=true. Priority-date year 0 is the USCIS "Prior Years" rollup. Built and maintained by EB5 Base; verify against the official XLSX on uscis.gov for definitive figures.

Monthly workbooks (26 published · USCIS originals)

Date is the inventory as-of day; muted line is when USCIS posted. Months labeled not posted were never published. Each link downloads the XLSX from uscis.gov.

I-526 / I-526E filings & EB-5 throughput

Two complementary quarterly releases: EB-5 filings detail, and All Forms throughput for the whole EB-5 family.

Open the I-526 explorer

Dataset 1 · I-526 filings detail — country × TEA category × month

A dedicated EB-5 quarterly workbook. One row per receipt month × country of birth × TEA set-aside category (Rural, HUA, Rural & HUA, Infrastructure, Unreserved), split by Form I-526 (standalone) and Form I-526E (regional center).18 quarters ingested so far. Latest data is available through Q1 2026 (covers receipts January 1, 2026 → March 31, 2026).

  • Best for: Demand modeling per set-aside category, country share of filings, receipt trends over time.
  • Limitations: No data on approvals, denials, or pending inventory — you need the throughput dataset for those.

Dataset 2 · Throughput & processing — EB-5 family

One giant quarterly "All Forms" workbook from USCIS covering every immigration form. For the EB-5 family it includes receipts, approvals, denials, completions, pending inventory, and median processing months for I-526 legacy, I-526 standalone, I-526E, I-829, and the I-956 regional-center forms. 9 quarters ingested so far. Latest data is available through Q1 2026.

  • Best for: Approval volumes, denial rates, processing-time trends, and pending inventory at the form-type level.
  • Limitations: No country or TEA-category splits — combine with Dataset 1 whenever you need to go below the whole-form level.

Throughput & processing summary

Download i526-processing-summary.csv

Suppressed USCIS cells appear with an empty count/stat and suppressed=true. Values shown as "-" or empty in the XLSX are treated as zero and omitted from the CSV. Built and maintained by EB5 Base; for definitive figures, verify against the XLSX on uscis.gov.

Quarterly releases (18 published · 18 filings files · 9 throughput files)

Each calendar year below has four quarter slots. Quarters labeled not posted were never published by USCIS (or have not been published yet for the current year). Each published quarter has up to two direct links to the XLSX on uscis.gov.

I-526 filings data: available through Q1 2026 — receipts from January 1, 2026 to March 31, 2026.

Throughput & processing: available through Q1 2026.

Official source

Everything above comes from the USCIS Immigration and Citizenship Data library page. The individual workbook links above go directly to the XLSX on uscis.gov; EB5 Base does not host copies of those files.

Conventions to know when you open the originals: In the workbooks, D or H markers mean suppressed (count under 10); "-" or empty cells mean zero. For I-485, priority-date years outside the 10-year window are rolled into "Prior Years". For I-526, TEA categories follow USCIS labels exactly: Rural, High Unemployment, combined Rural & High Unemployment, Infrastructure, Unreserved, and Unknown.

I-526 filings detail and EB-5 throughput come from two different USCIS products. Row counts differ by construction: filings data is disaggregated by country × TEA × month; throughput data is aggregated at the whole-form-type level for the quarter.
