U.S. Citizenship and Immigration Services (USCIS) announced a change to the filing locations for Form I-539, Application to Extend/Change Non-immigrant Status, effective October 7, 2026.
This update affects individuals submitting Form I-539 by mail. Applicants must now review the revised USCIS filing-address instructions to determine the appropriate location based on their reason for filing.
To provide applicants with time to adjust to the updated requirements, USCIS has established a 30-day grace period. During this transition period, the agency will accept applications sent to previously designated filing locations if they are postmarked on or before November 9, 2026.
Applicants, dependents, and immigration representatives should review this update carefully to avoid filing delays or rejection due to an incorrect mailing address.
1. Understanding Form I-539: Purpose and Eligibility
You can expand the section as follows:
Form I-539, Application to Extend/Change Non-immigrant Status, is used by eligible non-immigrants in the United States to request an extension of their authorized stay or a change to another eligible non-immigrant classification.
The form is commonly used by individuals who wish to remain in the United States beyond their current authorized stay or transition to another eligible non-immigrant category without departing the country.
Depending on the applicant’s circumstances, Form I-539 may be used for:
- Requesting an extension of stay in an eligible non-immigrant classification.
- Changing from one eligible non-immigrant status to another.
- Requesting reinstatement to F-1 or M-1 student status, when eligible.
- Applying for or extending certain dependent or family-member non-immigrant classifications.
- Requesting certain other immigration benefits specifically covered by the form.
Applicants must meet the applicable eligibility requirements and follow USCIS filing instructions. Filing Form I-539 does not automatically extend an individual’s authorized stay or grant the requested immigration status.
2. Effective Date of the Filing Address Update: October 7, 2026:
Effective October 7, 2026, USCIS revised the filing locations for Form I-539 applications submitted by mail.
Previously designated mailing addresses may no longer be appropriate for certain applications. Under the updated instructions, applicants must refer to the revised Form I-539 Filing Addresses page and select the mailing location based on the reason for filing.
The correct filing location may depend on the type of immigration request being submitted, rather than simply using an address from a previously filed application.
For this reason, applicants should not automatically reuse the mailing address shown on an earlier Form I-539 filing package or USCIS correspondence.
USCIS official filing-address page:
https://www.uscis.gov/i-539-addresses
Applicants should review the applicable category and mailing instructions before sending their applications.
3. USCIS Provides a 30-Day Grace Period for Previous Filing Locations
To minimize disruptions during the transition, USCIS has announced a 30-day grace period for applications submitted to previously designated filing locations.
Under this accommodation, USCIS will accept Form I-539 applications sent to any prior filing location if they are postmarked on or before November 9, 2026.
The important dates are:
| Filing milestone | Date |
| Updated filing locations announced | October 7, 2026 |
| Grace-period deadline | November 9, 2026 |
| Updated addresses should be used | For mailings after November 9, 2026 |
Understanding the Grace Period
Applicants who have already prepared or mailed their Form I-539 packages to a previous filing location may still benefit from the transition period.
For example:
- If an application is mailed to a previously designated filing location and is postmarked on November 6, 2026, it falls within the announced grace period.
- If an application is mailed to a previous filing location and is postmarked on November 10, 2026, it falls outside the announced grace period.
- If an application is prepared after November 9, 2026, the applicant should use the updated filing address applicable to the reason for filing.
The grace period is based on the postmark date, not the date the package is delivered to USCIS.
Applicants should retain mailing receipts and tracking information as evidence of the date the package was sent.
4. Finding the Appropriate Form I-539 Filing Address
Before submitting Form I-539 by mail, applicants should visit the official USCIS filing-address page.
The following steps can help identify the appropriate mailing location:
Step 1: Visit the USCIS Form I-539 page
Go to:https://www.uscis.gov/i-539
Review the form information and filing instructions.
Step 2: Open the filing-address page
Visit: https://www.uscis.gov/i-539-addresses
Step 3: Identify the reason for filing
Review the available filing categories and determine which one applies to your application.
Examples may include an extension of stay, change of status, reinstatement, or another eligible request.
Step 4: Review the applicable mailing instructions
Confirm the correct filing location and the mailing instructions provided for your specific filing category.
Step 5: Verify the delivery address
USCIS may provide different addresses depending on whether the package is sent through the U.S. Postal Service or a private courier service, such as FedEx, UPS, or DHL.
Applicants should select the appropriate address for their chosen delivery method.
5. Applicants Impacted by the Filing Address Update
The filing-address update is relevant to individuals and families submitting eligible Form I-539 applications by mail.
Examples include:
- B-1/B-2 Visitors: Individuals requesting an eligible extension of stay or change of status.
- F-1 Students: Students requesting reinstatement to F-1 status or another eligible benefit.
- M-1 Students: Students requesting reinstatement or another eligible benefit.
- H-4 Dependents: Eligible dependents requesting an extension of stay or change of status.
- L-2 Dependents: Eligible dependents requesting an extension of stay or change of status.
- E-2 Dependents: Eligible dependents requesting an extension of stay or change of status.
- V Non-immigrants: Individuals applying for or requesting an extension of stay in V classification.
- Eligible CNMI Residents: Individuals requesting an initial grant of status.
This list is illustrative and does not establish eligibility. Applicants must verify that their specific immigration classification and requested benefit qualify for Form I-539.
6. Important: Not Every Non-immigrant Category Uses Form I-539
Although Form I-539 is used for many extension and change of status requests, certain principal non-immigrant workers must use Form I-129 instead.
For example, USCIS generally requires Form I-129 for extension or change of status requests involving principal applicants in the following classifications:
- H-1B and H-1B1.
- H-2A and H-2B.
- H-3.
- L-1.
- O-1 and O-2.
- P classifications.
- Q-1.
- R-1.
- TN-1 and TN-2.
- Certain E-1 and E-2 principal applicants and E-3 principal workers.
Eligible dependents of certain principal non-immigrants may still need to file Form I-539 for their own extension or change of status.
For example, an H-1B principal worker generally files Form I-129, while an eligible H-4 dependent generally uses Form I-539 for an extension or change of status.
Applicants should review the applicable USCIS instructions to determine which form is required.
Filing Form I-539 when Form I-129 is required may result in rejection or denial.
7. Important Form Edition Update: Selecting the Correct Form I-539 Edition
In addition to the filing-address change, applicants should pay attention to USCIS’s separate update concerning the acceptable edition of Form I-539.
USCIS’s Form I-539 webpage currently states that, following a September 14, 2026 federal court order postponing implementation of the final rule concerning fixed periods of admission for certain non-immigrants, USCIS continues to accept the August 28, 2024 edition of Form I-539.
USCIS also states that it is not accepting the September 15, 2026 edition of Form I-539.
Applicants should therefore:
- Use the currently accepted August 28, 2024 edition of Form I-539.
- Ensure that all pages belong to the same form edition.
- Confirm that the edition date and page numbers are visible.
- Review the latest USCIS form instructions before submitting the application.
Using an incorrect form edition or combining pages from different editions may result in rejection.
This form-edition issue is separate from the October 7 filing-address update. Applicants must comply with both requirements.
8. Important Filing Considerations Before Mailing Form I-539
Applicants and immigration representatives should review the following items before sending a Form I-539 package:
1. Verify the filing address
Always check the latest USCIS filing-address instructions based on the reason for filing.
2. Confirm the correct form
Determine whether the applicant should file Form I-539 or whether another form, such as Form I-129, is required.
3. Check the form edition
Use the currently accepted form edition and ensure all pages are consistent.
4. Review the filing fee
Confirm the applicable USCIS filing fee and any required additional fees. Filing fees may vary depending on the application and filing method.
5. Include supporting documentation
Provide the required supporting documents based on the applicant’s immigration classification and requested benefit.
6. Obtain required signatures
Ensure that the applicant and any other required individuals have properly signed the application and applicable supplemental forms.
7. Use the correct delivery address
Verify whether the selected address is for U.S. Postal Service deliveries or private courier services.
8. Retain proof of mailing
Keep the shipping receipt, tracking number, and proof of the postmark date for future reference.
9. Consequences of Filing Form I-539 at the Incorrect Location
Submitting an application to an incorrect USCIS filing location may result in processing delays, rejection, or other filing complications.
Although USCIS has announced a grace period for applications sent to previous filing locations, that accommodation applies only to applications postmarked on or before November 9, 2026.
Applicants should not assume that USCIS will automatically forward an application sent to an outdated address or accept a filing made outside the announced grace period.
If an application has already been mailed to an incorrect location, the applicant should review the applicable USCIS instructions and seek guidance regarding the appropriate next steps.
10. Conclusion
USCIS’s October 7, 2026 update to Form I-539 filing locations is an important change for individuals and families submitting extension of stay or change of status applications by mail.
Although USCIS has provided a 30-day grace period for applications sent to previously designated filing locations, the accommodation applies only to applications postmarked on or before November 9, 2026.
Applicants should review the updated filing-address instructions, confirm the correct form edition, and ensure that their applications are properly prepared before mailing.
Taking these steps can help avoid unnecessary filing complications and delays in the immigration process.
