Sources we use
We use only primary, official sources: the Visa Bulletin charts as published by the U.S. Department of State and reproduced by USCIS, USCIS forms, fee schedules, policy manual and data library reports, Department of Labor wage rules, and the Immigration and Nationality Act and Code of Federal Regulations. We do not use law-firm blogs, forums or social media as sources of fact.
How calculators are checked
Every calculator uses published, standard formulas. The code is covered by automated tests that check known answers (for example, that the November 2026 USCIS chart lists EB-2 India at 15 January 2015 on the Dates for Filing chart, exactly as printed on the USCIS page). We show the formula next to each tool so anyone can verify the result by hand.
What we will not publish
- Advertising or referral links for immigration lawyers, consultants or visa services.
- Promises or guarantees about when a priority date will become current or when a case will be approved.
- Claims we cannot support with a source.
Updates and corrections
Each page shows the date it was last updated. The State Department publishes a new Visa Bulletin every month and USCIS designates its filing chart soon after; USCIS processing-time reports appear monthly. We re-run our parser when each new document appears and update the page dates. If you find an error, tell us through the contact page and we will review it and correct it.
