How we calculate

USCIS processing times: 50, 80 and 93%

USCIS publishes processing times for each form, category and office. We show three marks:

• 80% — the office time from the USCIS publication: 80% of cases are decided within it.
• 93% — the threshold from the same publication: if your case has been pending longer, USCIS accepts a case inquiry.
• 50% — the historical median: half of cases are decided faster. Shown only when it is known for the category.

One month = 30 days

USCIS publishes times in months, sometimes in weeks. To turn them into dates, we count a month as 30 days and a week as 7 days. stats.i-guide.org and I-GUIDE Pro count the same way, so the numbers match.

Time elapsed and the inquiry date

• Months elapsed = (today − filing date) ÷ 30.
• Time left to a mark = the mark − months elapsed.
• The date from which you can submit an inquiry to USCIS = filing date + the 93% time × 30 days.

The calculation runs in your browser; the filing date is not sent anywhere.

History of wait times

How a wait time changed over recent years comes from the ImmigrationTimes.org archive (CC BY 4.0 license) and our own snapshots of USCIS publications.

Queues and decisions

How many applications were filed, decided and are pending comes from USCIS quarterly reports (Immigration and Citizenship Data) and the USCIS monthly report to Congress. Quarterly reports come out several months late, so every number shows the date it refers to.

Publication date

The site currently uses the USCIS publication of September 17, 2026. The publication date is shown next to every calculation.

How we write status explanations

An explanation does not retell the USCIS text. It contains only what helps: what to do next, how long the step usually takes, pitfalls, and how the status affects your work permit, travel and court case. Facts come from sources: USCIS and EOIR websites, the Federal Register, analysis by attorneys. If there is nothing to add to the USCIS text, there is no explanation.

One number, one source

Every number is calculated in one place and is the same on every page of this site and on stats.i-guide.org. Every number has a date and a source.
