You have just received the news you’ve been waiting for: USCIS has approved your I-130 petition. It’s a moment of celebration! But for couples navigating the marriage-based green card process from outside the United States, approval is just the end of Chapter One.
Now, your case moves to Chapter Two: The National Visa Center (NVC).
Suddenly, your old USCIS receipt number (the one starting with IOE, MSC, or LIN) isn’t the most important number anymore. Now, you need your NVC case number. Without this number, you cannot log into the government portal, you cannot pay your fees, and you cannot schedule your interview.
But what happens if you haven’t received it yet? Or worse, what if you received the email but can’t find it?
In this comprehensive NVC case number guide, we will walk you through exactly what this number is, how to decode it, and the step-by-step process to find it if it’s missing.
ℹ️ Key Takeaways
- It’s Not the Same as USCIS: Your NVC case number is different from your USCIS receipt number. It usually starts with three letters (like MTL, CDJ, or LND).
- It Unlocks the CEAC Portal: You need this number + an Invoice ID to log into the Consular Electronic Application Center (CEAC).
- Wait Times Vary: In 2026, it typically takes 45 to 60 days after USCIS approval for the NVC to generate your case number.
- Check Your Spam: The “NVC Welcome Letter” is sent via email and often ends up in spam folders.
- Don’t Guess: Entering the wrong number too many times can lock you out of the system.
What is an NVC Case Number?
The NVC case number is a unique identifier assigned to your immigration file by the National Visa Center. The NVC is part of the U.S. Department of State (DOS), not the Department of Homeland Security (DHS).
Think of it as a baton pass. USCIS (DHS) approves your eligibility to apply for a green card. They then pass the baton to the NVC (DOS), who handles the actual visa application and document collection before sending you to a U.S. Embassy or Consulate for an interview.
Who Needs an NVC Case Number?
You only need this number if you are applying for a green card via Consular Processing.
- Consular Processing: The spouse seeking a green card lives outside the United States.
- Adjustment of Status: The spouse seeking a green card is already inside the United States.
Important Note: If you are applying for Adjustment of Status (filing Form I-485 from within the U.S.), you generally do not deal with the NVC. If you receive an NVC case number by mistake, you usually just notify them that you are adjusting status locally.

The Difference Between USCIS Receipt Number and NVC Case Number
It is very common to get these two confused. Here is how to tell them apart:
USCIS Receipt Number
- When you get it: Within 2-3 weeks of mailing your initial application.
- Format: 3 letters followed by 10 numbers (e.g., IOE-1234567890).
- Purpose: Tracks the progress of your petition (Form I-130) while it is being reviewed by USCIS.
NVC Case Number
- When you get it: After USCIS approves the I-130 and transfers the file to the State Department.
- Format: 3 letters followed by 10 numbers (e.g., LND-2026-123-456).
- Purpose: Allows you to access the CEAC system to submit the DS-260 form and financial documents.
When Do You Get an NVC Case Number?
In an ideal world, the transfer happens instantly. In reality, government systems take time to sync. Here is the typical NVC case number 2026 timeline:
- USCIS Approval: You receive a Notice of Action (Form I-797) stating your I-130 is approved.
- File Transfer: USCIS sends your physical or digital file to the NVC in Portsmouth, New Hampshire.
- Data Entry: The NVC receives the file and creates a record in their system.
- Welcome Letter: The NVC sends the “Notice of Immigrant Visa Case Creation” (often called the Welcome Letter) to the petitioner and the beneficiary (or their attorney/agent) via email.
Current Processing Time: As of early 2026, it takes approximately 45 to 60 days from the date of USCIS approval to receive your NVC Welcome Letter.
Scenario: Sarah (US Citizen) petitioned for her husband, Marco (in Italy). USCIS approved their case on January 15, 2026. They shouldn’t panic if they haven’t heard from the NVC by February 1st. They should likely expect their NVC case number around mid-March.
How to Find Your NVC Case Number (Step-by-Step)
If it has been more than 60 days since your approval and you still don’t have your number, or if you simply can’t find the email, follow these steps.
Method 1: The NVC Welcome Letter (Email)
The NVC has moved to an almost entirely digital process. They rarely mail physical letters anymore unless you did not provide an email address on your I-130.
- Sender: Look for emails from National Visa Center or an address ending in @state.gov.
- Subject Line: Usually contains “Notice of Immigrant Visa Case Creation.”
- Where to check: Check the inbox, spam, and junk folders for both the petitioner (the U.S. citizen/resident) and the beneficiary (the spouse abroad).
Method 2: The Public Inquiry Form (Best Method for Lost Numbers)
If you cannot find the email, the most reliable way to retrieve your NVC case number is by submitting a Public Inquiry. The NVC has largely shut down their public phone lines for status checks, so this online form is your primary tool.
- Go to the USCIS/State Department Public Inquiry Form.
- Enter your USCIS Receipt Number (from your I-797 approval notice).
- Enter the Petitioner’s and Beneficiary’s full names and dates of birth.
- In the “Question” box, write a simple message:
- “My I-130 was approved on [Date]. It has been over 60 days. I have not received a Welcome Letter. Please provide my NVC Case Number and Invoice ID.”
Response Time: In 2026, responses to inquiries typically take 1 to 2 weeks.
Method 3: Calling the NVC (Not Recommended)
While a phone number exists for the NVC, it is notorious for long hold times or simply playing a recording that tells you to use the website. If you are desperate, you can try, but be prepared for a wait.
- Phone: 603-334-0700
- Hours: 7:00 AM to 12:00 midnight EST, Monday through Friday.
🚀 Feeling Overwhelmed by Government Portals?
Moving from USCIS to the NVC involves new login IDs, new forms (DS-260), and complex document uploads. One mistake can delay your spouse’s arrival by months.
Greenbroad simplifies this. For a flat fee of $749, we organize your documents, fill out the forms, and guide you through the NVC stage so you don’t have to guess.
Decoding Your NVC Case Number
Your NVC case number isn’t random. It tells a story about where your interview will take place and when your file was opened. Understanding this can help you verify you have the right number.
The format is usually AAA-YYYY-JJJ-SSSS.
1. The Consulate Code (AAA)
The first three letters represent the U.S. Embassy or Consulate that will likely conduct the interview.
- LND: London, UK
- CDJ: Ciudad Juarez, Mexico
- MTL: Montreal, Canada
- MUM: Mumbai, India
2. The Year (YYYY)
These four numbers represent the year the NVC created your case.
- Example: 2026
3. The Julian Date (JJJ)
This is the trickiest part. These three numbers represent the specific day of the year the case was created, plus 500.
- To calculate the actual day, subtract 500 from this number.
- Example: If the number is 532, you calculate: 532 - 500 = 32. This means the case was created on the 32nd day of the year (February 1st).
4. The Sequence Number (SSSS)
The final digits are just a sequence number for the cases created on that specific day at that specific post.
Example: MTL2026532005
- MTL: Interview in Montreal.
- 2026: Created in the year 2026.
- 532: Created on February 1st (32nd day of the year).
- 005: This was the 5th case created for Montreal that day.
The “Other” Number: The Invoice ID
Getting your NVC case number is only half the battle. To log into the Consular Electronic Application Center (CEAC), you need two things:
- NVC Case Number
- Invoice ID Number
The Invoice ID is essentially your password. You cannot guess it, and it cannot be derived from other numbers. It will be located clearly on your NVC Welcome Letter (usually near the top right).
If you have your Case Number but lost your Invoice ID: You must use the Public Inquiry Form mentioned in Method 2 above. For security reasons, the NVC will generally not give Invoice IDs over the phone.
Common Mistakes to Avoid
When dealing with NVC numbers, small errors cause big delays. Here is what to watch out for in 2026.
1. Confusing Zeros and Letter ‘O’s
Government font styles can be confusing.
- NVC Case Numbers usually use numbers for the date section. If you see a circle in the middle section (e.g., 2026), it is the number zero.
- Consulate codes (the first three letters) are always letters.
2. Logging in Too Early
Sometimes you receive the Welcome Letter, but the system hasn’t fully updated. If you try to log in and get an error saying “Case not found,” wait 24 hours and try again.
3. Ignoring the “Termination” Warning
If you receive an NVC case number but do not contact the NVC for one year, they may begin the process of terminating your petition. Even if you aren’t ready to pay fees yet, log into the CEAC portal at least once every six months to keep the account active.
Next Steps After Receiving Your Case Number
Once you have your NVC case number and Invoice ID, the clock starts ticking on your responsibilities. Here is your checklist:
- Log into CEAC: Go to the Department of State website and log in.
- Choose Your Agent (DS-261): This simple form tells the NVC who to communicate with (usually the petitioner or an attorney). Note: In 2026, this is often automated or part of the initial setup.
- Pay Fees: You will see two fees:
- Affidavit of Support Fee
- Immigrant Visa Application Fee
- Note: These must be paid via a U.S. bank account.
- Submit Forms: Complete the DS-260 (Immigrant Visa Application).
- Upload Documents: Scan and upload civil documents (birth certificates, police records, marriage certificate) and financial documents (tax returns, I-864).

FAQ: Frequently Asked Questions
1. Can I get my NVC Case Number online without the Welcome Letter?
Not directly. There is no public database where you can type in your name and see the number. You must either wait for the Welcome Letter email or submit a Public Inquiry form to the NVC using your USCIS receipt number to request it.
2. How long does it take to get an NVC Case Number in 2026?
Currently, it takes between 45 to 60 days from the time USCIS approves your I-130 petition until the NVC generates a case number and sends the Welcome Letter.
3. Does an NVC Case Number expire?
The number itself doesn’t expire, but your case can be terminated. If you do not contact the NVC or log into the CEAC system for a period of one year, the NVC may begin the process of closing your case.
4. Is the NVC Case Number the same as the Visa Number?
No. The NVC Case Number tracks your application file. The Visa Number is the actual red number printed on the visa stamp in your passport after your interview is successful.
5. Why does my NVC Case Number start with different letters?
The first three letters correspond to the U.S. Embassy or Consulate where your interview will take place (e.g., LND for London, CDJ for Ciudad Juarez). This helps route your physical and digital file to the correct location.
Conclusion
Finding your NVC case number is a small but critical step in your immigration journey. It signifies that you have cleared the first major hurdle (USCIS approval) and are now on the path to your visa interview.
While the wait for the Welcome Letter can be frustrating, especially with the 2026 processing times, knowing how to decode the number and how to inquire if it goes missing puts you back in control.
