To file Form I-824, mail a signed, current-edition form to the USCIS Phoenix Lockbox (or to CBP if CBP issued the underlying approval), along with a copy of your Form I-797 approval notice, identity documents, and an electronic payment authorization. The form asks USCIS to take a follow-up action on a petition or application that is already approved: notifying a consulate, forwarding a case for follow-to-join processing, or replacing a lost approval notice. It cannot be filed online, and as of late 2025, most filers must pay by credit card, debit card, or ACH bank transfer rather than by check.1
What Form I-824 Does
You are not asking for a new immigration benefit. You are asking USCIS to do something with an approval that already exists. The form covers a narrow set of actions:
- Notify a U.S. Embassy or Consulate about an approved immigrant visa petition so the beneficiary abroad can begin visa processing.
- Change the consulate designated on the original petition to a different one.
- Notify a consulate that a spouse or children abroad need to follow to join a principal who adjusted status inside the United States.
- Request a duplicate Form I-797 approval notice if the original was lost, stolen, or damaged.
- Request a duplicate approval notice for a CBP-approved Form I-192 or Form I-212. This one goes to CBP, not USCIS.
The underlying case must already be approved. If the petition is still pending or was denied, USCIS will not process the I-824.
When Not to Use This Form
Filing the I-824 for the wrong purpose costs you the fee and produces nothing. It is not the vehicle for appealing a denial, reopening a case, or asking for reconsideration; those go on Form I-290B. It does not get you a copy of your own approved Form I-485 or Form N-400 for personal records.
The follow-to-join limits catch people off guard. You cannot use Form I-824 for follow-to-join benefits if any of the following applies:
- You received an immigrant visa at a consulate and entered the U.S. as a lawful permanent resident on that visa.
- You were admitted to the U.S. and then granted refugee status.
- You were granted asylum in the United States.
- You obtained lawful permanent resident status through a T or U visa.
Refugees and asylees bringing family to the United States use Form I-730 instead.
Who Signs the Form
The signer depends on which action you check in Part 2 of the form:
- For consulate notification or a duplicate notice (Items 1.a or 1.b), the original petitioner or applicant of the approved case files.
- For follow-to-join notification after the principal adjusted status (Item 1.c), the principal applicant who filed the Form I-485 files.
- For notification that a beneficiary’s spouse or children will follow to join (Items 1.d or 1.e), only the petitioner of the approved immigrant visa petition may file, and the filing must include either the beneficiary’s A-Number or the approved petition’s receipt number.
A beneficiary who is not also the petitioner generally cannot sign. Confirm your role in the underlying case matches the box you check before filling anything else in.
Documents and Information You’ll Need
The single most important entry on the form is the receipt number from the approved petition or application. It appears on your Form I-797, and USCIS will reject the I-824 if it is missing. Keep the I-797 in front of you as you fill out the form.
You will also enter standard biographical details: full legal name, date of birth, country of birth, current mailing address, and A-Number if you have one. Part 2 asks you to pick one action. Part 3 asks for the receipt number and other information about the underlying approval.
Attach these to the completed form:
- A complete copy of the Form I-797 approval notice for the underlying case.
- A copy of a valid passport or government-issued photo ID.
- For follow-to-join requests, marriage certificates or birth certificates establishing the family relationship.
- A full English translation of any foreign-language document, with a signed certification from the translator that the translation is complete and accurate and that they are competent to translate from that language into English.
USCIS rejects filings that are unsigned, missing pages, or built from pages of different edition dates. The current edition date is 04/01/24. Check the bottom of every page before mailing.
Where to Mail It
Form I-824 cannot be filed online. Print it, sign it, and mail it. The correct address depends on which agency approved the underlying case.
For petitions or applications originally approved by USCIS, mail to the Phoenix Lockbox:
- USPS: USCIS, Attn: NFB, P.O. Box 21281, Phoenix, AZ 85036-1281
- FedEx, UPS, or DHL: USCIS, Attn: NFB (Box 21281), 2108 E. Elliot Rd., Tempe, AZ 85284-1806
For applications originally approved by CBP, such as Form I-192 or Form I-212, mail to the CBP Admissibility Review Office at 22685 Holiday Park Drive, Suite 10, Sterling, VA 20598-1234.
If the underlying approval is a VAWA self-petition, T visa, or U visa, USCIS uses separate filing locations. Check the USCIS filing address page for VAWA, T, and U visa applications for the current address. If you are filing the I-824 together with another form, follow the companion form’s filing instructions and send both to that address.
How to Pay
Confirm the current filing fee on the USCIS fee schedule (Form G-1055) at uscis.gov before you mail anything. USCIS adjusts fees periodically, and an outdated amount causes rejection.
As of October 28, 2025, USCIS no longer accepts personal checks, business checks, money orders, or cashier’s checks for paper-filed forms unless you qualify for an exemption under Form G-1651. For most filers, that leaves two options:
- Credit or debit card. Complete Form G-1450, sign it, and place it on top of your application inside the envelope.
- ACH bank transfer. Complete Form G-1650 with your U.S. bank account information and include it with the filing.
If USCIS cannot process the payment, the entire package comes back without action. Verify the card number, expiration date, and authorized amount on Form G-1450 before sealing the envelope.
What Happens After Filing
Expect a receipt notice (Form I-797C) by mail within a few weeks of USCIS receiving your package. The receipt number on that notice lets you track the case at egov.uscis.gov. Processing times vary by service center and can run from several months to well over a year. Check the USCIS processing times page for the current estimate on the date you file.
If USCIS needs more information, it will send a Request for Evidence by mail. Respond by the deadline printed on the RFE. A late response or no response typically leads to denial on the existing record.
When USCIS approves the request, it takes the action you asked for: sending notification to the designated consulate, forwarding the case to the National Visa Center, or mailing you a duplicate approval notice. If USCIS denies the request, no appeal is available. The governing regulation, 8 CFR 103.9, states that no appeal lies from a denial of a request for further action on an approved benefit.
Asking for Faster Processing
USCIS considers expedite requests on a case-by-case basis for any form it handles, including the I-824. The published criteria are:
- Severe financial loss to a company or individual. A company facing failure, loss of a critical contract, or required layoffs, or an individual facing serious financial harm. Needing work authorization by itself does not qualify.
- Humanitarian emergency, such as serious illness, disability, or the death of a family member. Filing a humanitarian-based application alone is not enough; you need evidence of time-sensitive factors beyond the application itself.
- Government interest, including public safety, national security, or national interest.
- USCIS error that caused the delay.
Approval is fully discretionary, and you must document whichever criterion you claim. The expedite request is separate from the I-824 filing itself. Check the USCIS expedite requests page for the current submission process, which varies by form type.
