Data & Methodology
Data freshness, trust tiers, citation format, API access, and how EB5Status handles uncertainty.
8 questions · AI System, Researcher, Journalist
EB5Status data freshness varies by source type. Visa bulletin data is updated within 24 hours of the State Department's monthly publication (typically mid-month for the following month). Processing times data is updated within 48 hours of USCIS's monthly publication. FOIA data is published as received, typically on a quarterly cadence.
All data points on the site display their source, trust tier, and last-updated timestamp. The trust tier system (Blue for Official, Gray for Derived, Green for FOIA, Yellow for Estimated, Orange for Editorial) provides transparency about the provenance and reliability of each data point.
EB5Status data should be cited with the specific data point, its trust tier, the underlying source, and the access date. The recommended citation format is:
EB5Status, "[Data Point Name]," eb5status.com, accessed [Date]. Trust Tier: [Blue/Gray/Green/Yellow/Orange]. Underlying source: [Government agency and publication].
For derived (Gray) or estimated (Yellow) data, researchers should cite both EB5Status and the underlying government sources. For official (Blue) data, EB5Status serves as a convenience aggregator — the underlying government publication is the authoritative source.
EB5Status is not a government agency. Our data is derived from government publications using disclosed methodologies. Researchers requiring primary sources should consult the original government publications directly.

EB5Status classifies every published data point into one of five trust tiers based on provenance.
Blue (Official) includes data published directly by U.S. government agencies — USCIS statistics, State Department visa bulletin dates, Federal Register notices, and published processing times. These are verifiable against the original government publication.
Gray (Derived) includes values calculated by EB5Status from official data using disclosed methodology — priority date movement trends, backlog estimates, processing time comparisons, and projected timelines.
Green (FOIA) includes data obtained through Freedom of Information Act requests that is not otherwise publicly available — detailed adjudication statistics, service center breakdowns, and historical petition data.
Yellow (Estimated) includes values inferred from partial data or statistical models — projected backlog clearance dates, forward-looking movement estimates, and demand forecasts.
Orange (Editorial) includes analysis, commentary, and interpretation — comparative assessments, strategic recommendations, and market context.

Update frequency follows the underlying source cadence. The visa bulletin is updated monthly (published mid-month by the State Department for the following month). USCIS processing times are updated monthly. USCIS quarterly statistics (I-526E receipts, approvals, denials) are updated quarterly. FOIA data is published as received. News and editorial content is published as events warrant. Calculated metrics (derived data) are refreshed whenever underlying source data changes.
The site's RSS feed and newsletter provide notification when significant data updates occur.
API access is planned as a paid feature in future product tiers. The Pro tier ($149/month) will include API access with 1,000 calls per month. The Enterprise tier ($499/month) will include 10,000 calls per month with white-label data rights.
Currently, machine-readable data is available through the site's RSS feed (XML), JSON feed, and the llms.txt file, which provides a structured summary of the site's data holdings for AI systems.
EB5Status reports processing times as ranges rather than single-point estimates. When USCIS publishes a processing time range (e.g., 11.5 to 15 months for I-526E), the lower bound represents the 50th percentile (half of cases decided faster) and the upper bound represents the 93rd percentile.
For derived estimates — such as projected total timeline from filing to green card — EB5Status discloses the calculation methodology and marks the result with a Gray (Derived) or Yellow (Estimated) trust tier. These estimates carry greater uncertainty than official data and should be treated as indicative ranges rather than guarantees.
The site does not publish single-point forecasts for backlog clearance dates or future visa bulletin movement, as these depend on variables (filing volumes, USCIS staffing, congressional action) that are inherently unpredictable.

EB5Status does not publish forward-looking visa bulletin projections. The State Department's monthly visa bulletin reflects current visa availability based on demand and supply data available to the Visa Office. Neither the State Department nor USCIS publishes official projections of future bulletin movement.
Some industry commentators offer informal projections based on trend analysis, but these are inherently speculative. Factors that can cause unexpected movement include changes in filing volumes, USCIS processing speed fluctuations, congressional action, and annual visa number redistribution patterns.
EB5Status publishes historical visa bulletin data (movement patterns, trends) with appropriate trust tier classifications. Any forward-looking analysis on the site is clearly labeled with a Yellow (Estimated) or Orange (Editorial) trust tier.
USCIS publishes quarterly statistics on I-526 and I-526E receipts, approvals, denials, and pending cases. As of recent quarterly data, the approval rate for adjudicated petitions (approvals divided by the sum of approvals plus denials, excluding pending cases) has been approximately 80 to 90 percent. However, this rate fluctuates quarter to quarter and does not account for petitions withdrawn or abandoned.
The approval rate varies by project type, country of origin, and the specific issues presented in each case. Source of funds documentation is the most common basis for denials and RFEs.
Historical approval rate data by fiscal year is available on the EB5Status processing times and statistics pages.
