How many days do I have to contact the Department of Homeland Security (DHS) regarding my Self Check DHS Tentative Nonconfirmation (Mismatch)?

For a DHS Self Check mismatch, you must contact DHS or use your myE-Verify account to electronically submit documents to DHS that show your employment authorization within 8 federal government working days. To do this:

1. Log in to myE-Verify at https://myeverify.uscis.gov;
2. Click on myUploads and enter your E-Verify case number; 
3. Upload your documents not exceeding 4MB in a .jpg, .jpeg, .png, or .pdf format; and
4. Call DHS at 888-897-7781 (TTY: 877-875-6028) and tell the representative that you uploaded documents for your case.

Have your Further Action Notice open when you call DHS, so that you can refer to it.
