Here is a plain-English breakdown of the most common USCIS status messages:

Case Was Received -- USCIS has your petition or application. This is the first status you'll see. Keep your receipt notice (Form I-797) safe--you'll need the receipt number to track your case.

Biometrics Appointment Was Scheduled -- USCIS needs your fingerprints, photo, and signature. You'll receive an appointment letter in the mail. This is required for most green card applications and some visa applications.

Case Is Being Actively Reviewed -- An officer is looking at your case. This doesn't mean something is wrong--it's a normal part of processing. Most cases stay in this status for weeks to months depending on workload.

Request for Evidence Was Mailed (RFE) -- USCIS needs more documentation before making a decision. This is not a denial. You typically have 87 days to respond. Take this seriously: respond completely and on time.

Response to Request for Evidence Was Received -- USCIS got your RFE response and is reviewing it. Normal review time after an RFE response is 60-90 days.

Case Was Transferred -- Your case moved to a different USCIS service center or office. This is administrative and does not reset your place in the queue.

Case Was Approved -- Your petition or application was approved. Congratulations. Depending on what was filed, you may receive a physical approval notice, a green card, or an EAD card in the mail.

Card Was Mailed To Me -- Your physical card (green card, EAD, or travel document) is on its way via USPS. Delivery typically takes 7-10 business days.

Case Was Denied -- USCIS denied your application. You should receive a denial notice explaining the reason. Options include filing a motion to reopen, motion to reconsider, or appeal depending on the form type.

Case Was Reopened -- USCIS is reconsidering a previously closed or denied case, typically because you filed a motion or USCIS found an error.
