Case Processing Times

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.

Processing Times of Other Agencies

If your request requires U.S. Citizenship and Immigration Services (USCIS) approval, select the applicable Form and Service Center from the USCIS website for average processing times.

For H-1B, O-1 and TN petitions, select Form I-129 Petition for Nonimmigrant Worker and see the chart below to determine the service center.
For J-1 Change of Status applications, select Form I-539, Application to Extend/Change Nonimmigrant Status and see the chart below to determine the service center.

If your request requires Department of State (DOS) approval, refer to DOS website for information on visa appointment wait times and processing. Notify DIS if a scientist’s visa application is pending with DOS for more than 60 days.

NOTES	Abroad: The foreign scientist is overseas and not currently in the U.S. Change of Status: The foreign scientist is switching from one immigration classification (e.g. J-1) to another (e.g. H-1B) while remaining inside the U.S. Extension: The foreign scientist is already at NIH and continuing his/her stay. This is also known as a 'renewal'. Portability: The foreign scientist is currently in the U.S. in H-1B status with another employer and changing to NIH as the new employer. Under portability, the H-1B foreign scientist may be able to begin employment with NIH shortly after the DIS/ORS files an H-1B petition with the U.S. Citizenship and Immigration Services (USCIS), Department of Homeland Security (DHS) for new employment at NIH. If the foreign scientist qualifies for portability (check with DIS to determine eligibility), NIH does not have to wait for USCIS to approve the new employment, and thus the foreign scientist can transfer or "port" his/her current H-1B to NIH. SEVIS: SEVIS (Student and Exchange Visitor Information System) is the Department of Homeland Security's internet-based database that allows for electronic transmission of information and events about J-1 Exchange Visitors. It enables NIH to issue the Form DS-2019, Certificate of Eligibility for J-1 Status. Transfer: The foreign scientist is switching from one U.S. employer or sponsor to NIH.
