I-94 Land Border Reentry Guide
Understand what happens when an I-94 is shortened because of passport validity, when a new passport may support a new admission, why border 'flagpoling' is not a guaranteed extension procedure, and how the $30 land-border I-94 fee and automatic visa revalidation rules work.
Executive Summary & Core Land-Border Principles
A land-border crossing into Canada or Mexico followed by an immediate return to the United States (colloquially termed 'flagpoling') is not an administrative extension procedure under U.S. immigration law. Every physical return to a U.S. port of entry constitutes a formal request for a new admission, subject entirely to CBP inspection, discretion, and statutory admissibility determinations.
Effective September 30, 2025, the fee for an electronic Form I-94 application at land ports of entry increased from the historic $6 charge to $30 (comprising the $6 baseline fee plus an additional $24 statutory fee). Travelers whose I-94 admission periods were truncated due to passport expiration rules do not receive an automatic update upon passport renewal; they must seek a lawful new admission or file Form I-539/I-129 with USCIS.
Crucial distinction: If an I-94 discrepancy is the result of a clerical mistake made at initial admission, travelers should pursue correction through a CBP Deferred Inspection Site rather than risking a border crossing. Furthermore, Automatic Visa Revalidation (AVR) under 22 CFR § 41.112(d) allows readmission with an expired visa stamp only for contiguous territory travel of 30 days or less under strict regulatory conditions.
A Land-Border 'Run' Is Not an Automatic I-94 Extension
The term 'flagpoling' is commonly used online for a brief trip to Canada or Mexico followed by an attempt to seek a new U.S. admission. For U.S. immigration purposes, however, this is not a guaranteed extension procedure.
When a traveler approaches a U.S. port of entry after leaving the country, CBP conducts a new inspection. The officer determines whether the person is admissible and, if admitted, the applicable classification and authorized period of stay.
A traveler therefore should not describe a border trip as something that automatically converts a shortened I-94 into a longer I-94.
Passport Expiration and the I-94
A passport's validity can affect the period for which a nonimmigrant is admitted. Travelers should therefore compare the passport expiration date with the validity of the visa or underlying petition before travel.
The practical consequence is that a traveler can sometimes receive an I-94 ending earlier than the expiration date of the underlying petition or visa when the admission is limited by passport validity or another applicable rule.
After renewing the passport in the United States, the traveler still has the original admission record unless CBP separately corrects or replaces it. Simply obtaining a new passport does not automatically change the existing I-94.

First Ask: Is This an Error Correction or a New Admission?
This distinction should be made before considering a border trip. If CBP made a mistake during the original admission—for example, entered the wrong classification or an incorrect admission period—the issue is an I-94 correction question.
CBP's Deferred Inspection guidance specifically covers qualifying errors made at admission. A traveler can contact the appropriate Deferred Inspection Site without automatically leaving the United States.
If the existing I-94 was correctly issued based on the information and admission conditions at the time, but the traveler now wants a longer authorized stay, that is a different issue. An extension or change of status may need to be handled through USCIS.

The Land-Border I-94 Fee Is Now $30
The original $6 figure is outdated. CBP states that effective September 30, 2025, an additional $24 fee applies to Form I-94 applications at land border ports of entry, bringing the total cost to $30.
CBP's payment guidance states that the $30 total consists of the original $6 land-border I-94 fee plus the $24 fee established by the 2025 federal legislation.
The fee is associated with the I-94 application at a land port. It should not be confused with visa fees, ESTA fees, Canadian or Mexican entry fees, or any separate immigration-processing cost.
| Fee Component | Amount |
|---|---|
| Original land-border I-94 fee | $6 |
| Additional HR-1 statutory fee | $24 |
| Current total fee per applicant | $30 |
What a Legitimate Land-Border Reentry Looks Like
A traveler who genuinely needs to leave and return through a land port should treat the trip as international travel followed by a new request for admission—not as a guaranteed administrative I-94 renewal.
11. Check the destination country's entry requirements
Canada and Mexico have their own immigration and entry rules. U.S. admission rules do not guarantee admission to the neighboring country.
22. Review your U.S. immigration documents
Carry the current passport, visa where applicable, I-94, and supporting petition or status documents.
33. Check whether a new I-94 application is required
At a land port, CBP may require an I-94 application and the current $30 fee where the traveler is eligible and required to obtain one.
44. Approach the U.S. port of entry normally
Answer CBP questions truthfully and explain the genuine purpose of the return and the requested admission.
55. Expect inspection
CBP can review the passport, visa, petition, employment or study documents, prior travel history, and other admissibility factors.
66. Retrieve the new I-94 after admission
Check the electronic I-94 after returning and verify the class of admission and authorized period.
Documents to Carry
The appropriate document package depends on the immigration category and reason for travel. A traveler should carry enough evidence to demonstrate identity, current status, the purpose of admission, and any underlying petition or program.
Identity and primary travel document valid for at least 6 months beyond intended stay unless exempt.
The visa may remain valid for entry; never detach or tamper with a visa page inside an expired passport.
Official travel document supporting the requested nonimmigrant classification.
Demonstrates previous lawful admission history and authorized stay dates.
Essential for petition-based categories including H-1B, L-1, O-1, and TN classifications.
Mandatory for F-1 students seeking readmission.
Mandatory for J-1 exchange visitors.
Recent pay statements and employer verification letter verifying ongoing qualifying employment.
Certified marriage or birth certificates for H-4, L-2, TD, or other dependent family members.
Automatic Visa Revalidation: The Limited 30-Day Rule
Automatic visa revalidation is not a visa extension and is not the same thing as receiving a new visa. It is a limited regulatory mechanism that can allow certain nonimmigrants with expired visas to seek reentry after brief travel to Canada, Mexico, or an applicable adjacent island.
The Department of State states that a qualifying traveler generally must have made a brief trip of 30 days or less and possess a valid admission record. The traveler must also satisfy the other applicable requirements and exclusions.
The original content incorrectly characterized AVR as an automatic right to return with an expired visa whenever the traveler has a valid I-94/I-797. The rule is narrower.
Canada and Mexico Are Separate Immigration Systems
A traveler who crosses the northern or southern U.S. border must also comply with Canadian or Mexican immigration requirements. U.S. law does not grant an automatic right to enter Canada or Mexico merely because the person wants to return to the United States.
CBP advises travelers to consult the destination country regarding its own entry requirements. This is particularly important when the traveler is a national of a country requiring a visa, electronic authorization, or other permission for entry into the neighboring country.
The destination country's decision can therefore affect whether a planned short border trip is feasible.
What Happens If Your Previous I-94 Has Already Expired?
The original guide stated that an expired I-94 automatically causes a visa cancellation under section 222(g) and automatically creates a three- or ten-year bar. That is too absolute.
The Department of State explains that remaining beyond the authorized stay can automatically void or cancel a visa under INA 222(g), subject to exceptions such as a timely filed extension or change-of-status request.
The unlawful-presence analysis is separate and depends on the facts. Three- and ten-year bars under INA 212(a)(9)(B) are not triggered simply because a traveler crossed an I-94 expiration date without examining the duration, age, exceptions, and other statutory requirements.
A person whose I-94 has expired should not use a border crossing as a routine repair strategy. The case should be reviewed before departure.
Border Reentry vs Deferred Inspection vs USCIS
| Problem | Potential Route | Why |
|---|---|---|
| CBP made a wrong I-94 classification or admission date | Deferred Inspection | |
| Traveler needs additional authorized time while remaining in the U.S. | USCIS extension procedure | |
| Traveler genuinely needs to travel and return | Port-of-entry inspection | |
| Visa has expired but traveler may qualify for AVR | Automatic Revalidation | |
| Prior I-94 has already expired | Case-specific immigration advice |
Common Land-Border I-94 Myths
No. A return to the United States is a new admission process subject to CBP inspection and discretion.
No. Effective September 30, 2025, CBP states that the total land-border I-94 fee is $30.
No. A passport renewal does not automatically rewrite an existing CBP admission record.
Not necessarily. If CBP made an admission-record error, Deferred Inspection is the appropriate correction channel to consider.
No. It is a limited rule, and CBP still determines admission.
No. Other conditions and exclusions apply.
Too broad. The unlawful-presence bars have specific statutory requirements and exceptions.
No. CBP determines the period of admission under the applicable rules at the time of admission.
No. Visa, destination-country, transportation, and other costs can apply separately.
A traveler should describe the actual purpose of travel and requested admission truthfully. Do not use a misleading description.
Check Your I-94 After Every Admission
CBP provides an electronic I-94 system for travelers to retrieve their arrival/departure record. After a new land-border admission, the traveler should retrieve the record and verify the classification and authorized period.
CBP also notes that land departures may not always be captured accurately in its electronic systems. Travelers who depart the United States by land and later need to demonstrate the departure should preserve evidence such as foreign entry stamps, transportation tickets, pay records, or other relevant receipts.
Before Attempting a Land-Border Reentry
11. Determine whether you actually need a new admission
If the existing I-94 contains a CBP error, consider Deferred Inspection first.
22. Check the current I-94
Verify the exact classification and authorized-stay date.
33. Verify passport and visa validity
Check whether the current passport, visa, and petition documents support the intended admission.

55. Review AVR eligibility if relying on an expired visa
Verify every automatic-revalidation condition and exclusion.
66. Prepare supporting immigration documents
Carry the documents appropriate to the classification.
77. Account for the $30 I-94 fee
The current land-border I-94 fee is $30 where an I-94 application is required.

Legal & Compliance Disclaimer
This guide provides general information about CBP admission, I-94 records, land-border travel, and automatic visa revalidation. It is not individualized immigration or travel advice. A person seeking admission at a U.S. port of entry is inspected by CBP and is not guaranteed admission or a particular period of stay. A land-border trip can also involve Canadian or Mexican immigration requirements. Where the underlying issue is an existing CBP admission-record error rather than a need for a new admission, Deferred Inspection may be the more appropriate route.
