I-821D
Case Was Received
DACA
What this means
USCIS has your application and created a case file. This is the starting line — they have not decided anything yet. A receipt notice (Form I-797C) should arrive by mail or in your online account.
What to do next
Keep your receipt notice. Create or check a myUSCIS account so you can see updates online. You usually do not need to contact USCIS yet — just wait for the next notice (biometrics, RFE, or a decision).
