My I-526 was approved in December but USCIS still has not sent my EB-5 case to the NVC. What can I do?

You can reach out to IPO via email but this is what we seeing now; very slow to get file from IPO to NVC. Not clear whether delay is at IPO or NVC intake, or both.

The typical time for transfer to the National Visa Center is approximately 30-45 days. My suggestion is that you reach out to the NVC as soon as possible to see if the approval was transferred for consular processing. Otherwise, you will have to file an application for action on an approved application or petition.

Ask your lawyer to intervene.

Push USCIS by calling the Contact Center and send an email to researchnvc@state.gov.

You can email the NVC and ask them to request the file from USCIS.

You can file a writ of mandamus action in federal court to compel them to forward your case to the National Visa Center.

We actually just resolved this issue for a client who had his case ping ponging back and forth between the USCIS and the NVC. We filed Mandamus and less than two months later, everything got resolved.

Bug them. Email NVC weekly. Email the IPO.

A mandamus here might be best. Congressional inquiries seem to not work. The file could be lost. Consulting a litigation attorney might be the most efficient way to handle.
