The Border Crossing Card, SENTRI membership and TN visa are often discussed together because all three are especially relevant to Mexican citizens, but they are not interchangeable. The Border Crossing Card is a B-1/B-2 visitor document. SENTRI is a trusted-traveler program that can provide expedited processing at designated border lanes for approved low-risk travelers. TN is a work-authorized nonimmigrant classification for qualifying Mexican and Canadian professionals under the USMCA framework. Using the wrong document for the wrong purpose can create serious immigration problems.
This guide focuses on the border and professional-travel questions that are specific enough to deserve their own page, while the broader U.S. visa guide for Mexican citizens covers B-1/B-2, other work visas and permanent-residence pathways.

Mexico Is Not an ESTA Country
Mexican citizens are not eligible for ESTA based on Mexican nationality because Mexico is not part of the Visa Waiver Program. For ordinary visitor travel, Mexican nationals generally need a B-1/B-2 visa, a qualifying Border Crossing Card or another valid document appropriate to the trip.
The U.S. Department of State currently lists B-1/B-2 visas for Mexican nationals as multiple-entry visas with a 120-month validity period when issued under the reciprocity schedule. Visa validity is different from the period of stay authorized by U.S. Customs and Border Protection after admission.
What Is the Border Crossing Card?
The Border Crossing Card, formally the DSP-150 and commonly called the BCC, laser visa or “mica,” is a special document for qualifying Mexican applicants. The Department of State describes the DSP-150 as both a Border Crossing Card and a B-1/B-2 visitor visa. The laminated card is generally valid for ten years, except for certain cards issued to children at a reduced fee.
The BCC is not a work permit and does not create permanent immigration status. It is used for temporary B-1/B-2 visitor purposes and remains subject to the same basic eligibility principles that apply to visitor visas.
Who can qualify for a BCC?
According to the Department of State and CBP, BCCs are issued only to applicants who are both citizens of Mexico and residents in Mexico. The applicant must meet the eligibility standards for B-1 and/or B-2 classification, plan a temporary stay and possess a valid Mexican passport at the time of application.
This means that residence in Mexico alone is not enough. A foreign national living in Mexico does not become eligible for a BCC simply because of Mexican residence. The BCC is nationality-specific.
Current BCC fees
The Department of State currently lists the Border Crossing Card application fee at $185 for applicants age 15 and older. For qualifying Mexican children under age 15, the fee is $15 when at least one parent or guardian holds a valid BCC or is applying for one. A card issued at the reduced fee is valid for ten years or until the child reaches age 15, whichever comes first. Paying the full fee can result in the full ten-year validity, subject to issuance.
| Applicant | Current Department of State fee | General validity rule |
|---|---|---|
| Age 15 or older | $185 | Generally up to 10 years |
| Qualifying child under 15 using reduced fee | $15 | 10 years or until age 15, whichever comes first |
Can a Border Crossing Card Be Used for Air Travel?
Old online summaries often say that a BCC can only be used at the land border. That is too simplistic. CBP states that Mexican citizens, including children, must present a passport with a visa or Border Crossing Card when traveling by air or sea. CBP also states that the BCC can serve in place of a nonimmigrant visa and, together with a passport, meets the document requirements for entry at land, air and sea ports of entry.
For direct entry from Mexico by land, pleasure vessel or ferry, Mexican nationals may in certain circumstances present the BCC as a stand-alone document without a passport. Travelers should still confirm the documentation required by the carrier and CBP for the exact route they plan to use.
BCC Border-Zone Rules and the I-94
Another common source of confusion is the idea that every BCC trip is automatically limited to the same mileage and the same number of days. Border-area admission rules depend on the traveler’s documentation and how far into the United States the person intends to travel. When an I-94 is required, the traveler must follow the admission terms issued by CBP.
The safest rule is operational: do not rely on an old blog table that says “25 miles for 30 days” as if it covers every trip. Before traveling beyond the immediate border area, check current CBP requirements and obtain the appropriate I-94 when required. The BCC does not replace the traveler’s obligation to comply with the authorized admission period.
What Is SENTRI?
SENTRI—Secure Electronic Network for Travelers Rapid Inspection—is a voluntary CBP Trusted Traveler Program for pre-approved, low-risk travelers. Approved members can use designated expedited vehicle and pedestrian processing lanes at participating ports along the Southwest border.
SENTRI does not replace a visa, BCC, passport or immigration status. It is an expedited inspection program. A traveler still needs the underlying documentation and immigration eligibility required for admission.
Current SENTRI fee
The old $122.25 SENTRI fee is obsolete. CBP changed the fee structure effective October 1, 2024. The current SENTRI application fee is $120 for adults. For applicants under age 18, the fee is $0 when the minor’s application includes the parent or legal guardian’s Trusted Traveler Programs application ID or membership number as required by CBP.
CBP also states that registering a vehicle as part of the initial SENTRI application does not carry a separate vehicle-registration fee. Adding a vehicle after the initial application currently carries a separate $42 processing fee.
| SENTRI item | Current CBP fee |
|---|---|
| Adult application | $120 |
| Qualifying applicant under 18 | $0 |
| Vehicle added after initial application | $42 |
SENTRI eligibility is based on risk assessment
SENTRI approval is not automatic. CBP conducts a background and admissibility review and may deny or revoke membership when an applicant does not meet program standards. Applicants should use the official Trusted Traveler Programs portal and provide complete, accurate information.
Mexican nationals in SENTRI may also have access to certain Global Entry benefits only under the rules CBP publishes for Mexican participants. CBP specifically notes that a Mexican national in SENTRI must apply for Global Entry through the TTP account to obtain Global Entry benefits.
SENTRI Does Not Guarantee Admission
SENTRI speeds inspection; it does not remove CBP’s authority to inspect the traveler or determine admissibility. A SENTRI member may still be referred for additional inspection. The traveler must continue to comply with the immigration conditions tied to the passport, visa, BCC or status being used.
Membership also does not authorize employment, extend a period of stay or cure a prior immigration violation. It is a border-processing benefit, not an immigration classification.
TN Visa for Mexican Professionals
The TN visa is completely different from a BCC or SENTRI membership. TN is a temporary work classification for qualifying citizens of Mexico and Canada who will perform professional-level services in an occupation listed under the USMCA framework.
USCIS states that Mexican citizens residing outside the United States must apply for a TN visa at a U.S. embassy or consulate. The applicant must document the professional activity to be performed in the United States and must satisfy the qualification standard for the listed profession. If the profession requires a baccalaureate or licenciatura degree, experience cannot automatically substitute for that degree unless the profession’s specific rule allows an alternative credential.
TN is nationality-based, not residence-based
A person does not qualify for TN merely because he or she lives in Mexico or works for a Mexican company. The principal TN applicant must be a citizen of Mexico or Canada and must meet the professional requirements for the qualifying occupation.
TN has no H-1B lottery
TN classification is not subject to the H-1B annual numerical cap or electronic registration lottery. That can make TN a practical option for Mexican professionals who fit one of the listed professions and have a qualifying U.S. professional role. It is not necessarily “better” than H-1B in every case, because the two classifications have different legal requirements and different immigration-intent considerations.
TN duration and renewals
TN admission may generally be granted for up to three years at a time. Extensions may be available when the employment and eligibility continue, but TN remains a temporary nonimmigrant classification. Applicants should avoid describing it as “renewable indefinitely” without qualification because every future visa issuance, admission or extension must independently satisfy the applicable requirements.
BCC vs. SENTRI vs. TN
| Document or program | Main purpose | Work authorized? | Who it is for |
|---|---|---|---|
| Border Crossing Card | Temporary B-1/B-2 visitor travel | No | Qualifying citizens and residents of Mexico |
| SENTRI | Expedited border inspection | No | Approved low-risk travelers who meet CBP program requirements |
| TN visa/status | Temporary professional employment | Yes, for the qualifying TN employment | Qualifying Mexican or Canadian citizens in listed USMCA professions |
Common Errors to Avoid
- Using the old $122.25 SENTRI fee: the adult fee has been $120 since October 1, 2024.
- Calling SENTRI a visa: SENTRI is an expedited inspection program, not immigration status.
- Calling the BCC a work permit: the BCC is a visitor document.
- Assuming the BCC is land-only: CBP publishes specific rules for use with a passport at air and sea ports as well.
- Assuming anyone living in Mexico can obtain a BCC: the Department of State says applicants must be citizens of and resident in Mexico.
- Assuming anyone in Mexico can get TN status: TN is based on Mexican or Canadian citizenship and a qualifying USMCA profession.
- Using fixed consular wait times: appointment estimates change and should be checked on official tools.

How to Apply for a Border Crossing Card
The BCC application uses the nonimmigrant visa process established by the Department of State. Applicants complete Form DS-160, pay the applicable fee, follow the scheduling instructions used by the U.S. mission in Mexico and present the required identity and supporting documents. The applicant must have a valid Mexican passport at the time of application.
A BCC application is still a B-1/B-2 application for legal purposes. The applicant must establish eligibility for temporary visitor classification. The card format does not lower the legal standard or guarantee approval for someone who would not otherwise qualify for B-1/B-2 status.
When Is an I-94 Needed With a BCC?
The I-94 question depends on the type and extent of travel. CBP uses the I-94 admission record to document status and the authorized period of stay for many nonimmigrant admissions. Travelers who plan to go beyond the geographic or time limits applicable to short border-area entry should check the current CBP rules before departure and obtain the required I-94 when applicable.
Travelers should not use the expiration date on the BCC as the departure deadline. The card may remain valid for years while a particular admission is authorized for a much shorter period. When CBP issues an electronic I-94, the traveler should review it after entry and keep the admission information consistent with the intended trip.
BCC Travel by Air: What the Official Rule Means
CBP’s current guidance is clearer than many older travel blogs. Mexican citizens traveling by air and sea are required to present a passport with a visa or Border Crossing Card. The BCC can serve in place of the nonimmigrant visa when combined with the passport. This means a categorical statement that “BCC holders cannot enter through airports” is inaccurate.
Airline document checks and CBP admission are separate stages. A carrier may verify documents before boarding, and CBP makes the immigration admission decision upon arrival. Travelers should carry the valid Mexican passport and BCC and should confirm any carrier-specific documentation requirements before travel.
How SENTRI Applications Work
SENTRI applications are submitted through the official Trusted Traveler Programs portal. The applicant creates a TTP account, completes the application, pays the applicable fee and undergoes CBP vetting. If conditionally approved, the applicant follows the program instructions for the interview and final review.
Conditional approval is not the same as final membership. CBP may ask questions about identity, travel history, residence, customs issues and other information relevant to the risk assessment. Applicants should disclose information completely and accurately because omissions or inconsistencies can affect approval or future membership.
Vehicle registration for SENTRI lanes
A vehicle used in SENTRI lanes must meet the program’s registration requirements. CBP currently states that registering a vehicle as part of the initial SENTRI application carries no separate fee. A vehicle added after the initial application carries a $42 processing fee. Vehicle inspections are no longer universally mandatory, but CBP retains authority over the program and the use of SENTRI lanes.
Who Can Use a SENTRI Lane?
Every person in the vehicle must have the documentation and program eligibility required for the lane being used. One person’s SENTRI membership does not turn unapproved passengers into SENTRI members. Families who cross together should make sure each traveler has the appropriate trusted-traveler status and immigration documents.
Program misuse can lead to loss of SENTRI privileges and can create broader customs or immigration consequences depending on what occurred. Members should follow the lane rules, declare goods as required and keep their TTP profile current.
SENTRI and Global Entry for Mexican Nationals
The programs share some infrastructure but should not be treated as identical. CBP states that U.S. citizens and lawful permanent residents who are SENTRI members may receive Global Entry benefits when the necessary fingerprints and document information are on file. A Mexican national in SENTRI must apply for Global Entry through the TTP account to obtain Global Entry benefits.
That distinction matters because a traveler may be eligible to use SENTRI lanes at the land border without automatically having the same airport processing benefits as another category of member.
Applying for a TN Visa as a Mexican Citizen
A Mexican TN applicant normally applies for the visa through a U.S. embassy or consulate. The application should document the U.S. professional activity, the employer or contracting entity, the applicant’s Mexican citizenship and the education or credentials required by the listed USMCA profession.
The employer letter is central because TN classification is tied to specific professional activity. It should accurately describe the position, duties, expected period of employment and how the role fits the qualifying profession. Generic job titles are not enough if the actual duties do not correspond to the profession listed under the agreement.
Education and professional credentials
USCIS explains that when a listed profession requires a baccalaureate or licenciatura degree, experience cannot simply replace the degree unless the profession’s rule expressly allows an alternative. Foreign credentials may need evaluation when the education was completed outside the United States, Canada or Mexico.
Some professions use licenses or other credentials in addition to or instead of a general degree requirement. Applicants should check the qualification standard for the exact profession rather than assuming that every TN occupation requires the same evidence.
TN Versus H-1B for Mexican Professionals
TN and H-1B can both authorize professional employment, but they operate differently. H-1B generally requires a specialty occupation and, for many employers, participation in the annual cap registration process. TN has no H-1B-style annual lottery but is limited to the professions listed in the USMCA framework and to citizens of Mexico or Canada.
H-1B also has a formal concept of dual intent that can make it easier to pursue permanent residence while maintaining H-1B status. TN is a temporary classification, so green card planning can require more careful handling of travel, visa applications and intent. A worker considering a long-term immigrant strategy should not switch classifications solely because one appears administratively easier in the short term.
Can a BCC Holder Later Apply for TN?
Yes, if the person independently qualifies for TN. Holding a BCC does not prevent a future TN application, but the BCC itself does not provide any TN benefit. The applicant must satisfy the TN requirements and obtain the appropriate TN visa and admission for professional employment.
The reverse is also true: having TN status does not eliminate the rules governing later visitor travel. Each classification has its own purpose and admission conditions.
When to Use the General Mexico Visa Guide Instead
This page is intentionally focused on BCC, SENTRI and TN. Applicants researching family-based immigration, H-2A/H-2B, F-1 study, E-1/E-2 or green card categories should use the broader U.S. visa for Mexican citizens guide. Keeping the two pages separate prevents a border-travel guide from becoming an unfocused list of every visa category.
Practical Checklist Before a Border Trip
- Confirm that the passport, visa or BCC is still valid for the planned trip.
- Check whether the travel route requires a passport together with the BCC.
- Determine whether an I-94 is required for the planned destination and duration.
- If using SENTRI, confirm that every traveler and vehicle meet the program requirements.
- Do not use a visitor document for employment.
- If traveling for TN employment, carry the documentation appropriate to the TN visa and admission.
- Check current CBP and Department of State guidance before relying on an old border-zone or fee table.
