Notice Explaining USCIS Actions Was Mailed
Short answer
This status means USCIS mailed you a letter about an action it took on your case, and the message does not say which action. USCIS publishes no list of the notices behind it, so the letter is the only reliable answer. It could be a request for evidence, a notice of intent to deny, a transfer or an appointment, among others. Watch your mail and your USCIS online account. If Case Status Online says the notice was sent more than 14 days ago and it has not arrived, ask USCIS for it.
- Notice not arrived 14 days after the date on Case Status, USCIS says to contact it
- If it is a NOID 30 days longest deadline to respond; 33 days if mailed
- If it is an RFE 84 days longest deadline to respond; 87 days if mailed
- Report a move to USCIS 10 days deadline after you change address

What this status means
“Notice Explaining USCIS Actions Was Mailed” tells you two things: USCIS took some action on your case, and it mailed you a letter about it. It does not say what the action was.
Three points about it:
- It does not say whether the news is good or bad. Approvals and denials have their own status messages.
- USCIS does not publish what this message covers, so no website, including this one, can tell you for sure which letter you will get.
- The letter may have a deadline, and the clock on some notices starts the day USCIS mails them.
What the letter could be
These are possibilities, not a diagnosis. The list comes from the notice types in the USCIS Policy Manual and on the USCIS page about Form I-797 types:
| Possible notice | What it would tell you | What it would ask of you |
|---|---|---|
| Request for evidence (RFE) | What evidence is missing, with examples | Send it by the date on the notice |
| Notice of intent to deny (NOID) | The reasons USCIS intends to deny, and adverse information it relies on | Respond by the date on the notice |
| Notice of intent to revoke or rescind (NOIR), or to terminate (NOIT) | That USCIS plans to revoke, rescind or terminate something on your case, and why | Respond by the date on the notice |
| Request for an original document | Which original USCIS wants to see | Send it by the deadline, or USCIS may deny the case as abandoned |
| Notice of action (Form I-797C) | A transfer of your file, a reopened case, an appointment or a rejected filing | Follow its instructions |
On the last row, USCIS says ignoring the instructions in a Notice of Action might delay your case. The I-797C also states that it does not grant any immigration status or benefit.
What to do now
- Check your USCIS online account. If you filed online, USCIS says the account gives you access to most notices it sends. If you filed on paper, you can link the case to an account to see its status and history.
- Watch your mail. USCIS notices cannot be tracked through USPS or UPS, so there is no tracking number.
- After 14 days, ask for it. If Case Status Online says the notice was sent more than 14 days ago and you do not have it, submit a case inquiry on e-Request in the category for a notice not received by mail. If you do not know your receipt number, call the Contact Center instead.
- Check the address USCIS has. You must report a move within 10 days, through the change of address page. A USPS change of address does not update USCIS, and USCIS says USPS will not forward mail from USCIS.
- Call the USCIS Contact Center if you cannot use the online tools: 800-375-5283, Monday to Friday, 8 a.m. to 8 p.m. Eastern. It lists a notice you did not receive among the requests it handles.
When the letter arrives
Read it the day it comes. These are the parts that tell you what kind of letter it is and what it asks:
| Look for | Why it matters |
|---|---|
| The form name at the top, such as I-797C or I-797E | USCIS uses the I-797E to request evidence and the I-797C for receipts, rejections, transfers, reopened cases and appointments |
| Your receipt number | It tells you which case the letter is about, if you have more than one |
| A deadline or an appointment date | It is the date that counts, not the date you received the letter |
| The address for a response | Send any response there, or upload it through your online account if the letter says you can |
Keep the original letter with your case papers. An I-797C states that it does not grant any immigration status or benefit, so it is a record of an action, not proof of status.
Deadlines, if the letter asks for a response
The date that counts is the one printed on the letter, not the day it reached you. The USCIS Policy Manual caps it: up to 12 weeks (84 days) for most RFEs, 30 days for an RFE on an I-539 or I-601A, and 30 days for a NOID. When the notice comes by mail, USCIS adds 3 days for the mail (87 or 33 days in all). When it is served in your online account, the clock starts the day it is uploaded, with no extra days.
Your answer has to arrive by that date; sending it is not enough. An answer uploaded through your online account counts as received the day you submit it. Without an answer in time, USCIS may decide the case on the record or deny it as abandoned. How to answer an evidence request is on our RFE status page.
What usually happens next
There is no single next step, because it depends on the letter. While you wait, keep in mind:
- USCIS does not research cases that are still within normal processing times. Compare yours on the USCIS processing times page or with our pages by form, such as I-485 processing time and N-400 processing time.
- If the letter never arrives because the post office returned it, the status may change to “Notice Was Returned To USCIS Because The Post Office Could Not Deliver It”. Then fix your address with USCIS and ask for the notice again.
The status messages that can come next
Each is explained in the status messages index:
- Response To USCIS’ Request For Evidence Was Received
- Case Was Transferred And A New Office Has Jurisdiction
- Case Was Reopened
- Case Is Ready To Be Scheduled For An Interview
- Case Was Approved
- Case Was Denied
The YourCaseStatus app (coming soon) will alert you when your status changes.
Frequently asked questions
Is 'Notice Explaining USCIS Actions Was Mailed' good news or bad news?
The message does not say. It only tells you that USCIS sent a letter about something it did on your case. The letter could ask you for something, tell you about a transfer or an appointment, or explain a problem. Read it before drawing conclusions.
Does this status mean my case was denied?
Not necessarily, and the message alone cannot tell you. USCIS has a separate 'Case Was Denied' message, and a denial comes with a decision notice. Wait for the letter, or look for it in your online account.
Can I see the notice online before it arrives?
If you filed online, USCIS says your online account gives you access to most notices it sends you. For a paper filing, your account can show the case status and history, but USCIS does not promise the notices.
How long should I wait for the letter?
USCIS says to contact it if Case Status Online shows a notice was sent more than 14 days ago and you have not received it. USCIS notices cannot be tracked through USPS or UPS.
Is there a deadline in this notice?
There may be. If the letter is a request for evidence or a notice of intent to deny, it has a response deadline, and for a mailed RFE USCIS counts the clock from the day it mailed the notice. That is why a missing letter is worth chasing early.
