Using This Chart
To use this chart, locate the type of case or request that you filed in the leftmost column under the heading “Case/Visa Type.” The second column, “DIS Processing Time,” shows the average time it takes DIS to process that type of case. In addition, the chart indicates if other agencies or organizations are involved in the process.
DIS processing times begin when a complete request is received in our office. However, in some instances, a complete request may take longer than the printed times due to the uniqueness of the case. Please note that unless otherwise indicated, all days listed in the chart are “business” days.
To find the day that DIS received your case, your Institute/Center's (IC) Key Contact (KC) can access the DIS online case status and reports system. See About DIS Processing Times for more information on choosing a realistic start date, checking the status of a case, and other questions.
A chart showing the workflow for case processing can be found in the Poster Gallery.
