This article previously described a procedure announced by the US Consulate in Ciudad Juarez in November 2008. It also listed an old appointment website, a telephone number, and categories of applicants who could or could not apply in Mexico. Those instructions are historical and should not be used to plan a current visa application.
What is a third country national visa application?
A third country national (TCN) visa application generally means that a person applies for a US visa at an embassy or consulate in a country other than the person’s country of nationality or residence. For example, a citizen of another country who is temporarily in the United States and wants to apply for a new visa stamp at a US consulate in Mexico may be seeking third country processing.
Where should a nonimmigrant visa applicant apply now?
On July 15, 2026, the US Department of State announced updated instructions for nonimmigrant visa applicants. Effective immediately, applicants should schedule their visa interviews at a US embassy or consulate in their country of nationality or residence.
Nationals of countries where the US government is not conducting routine nonimmigrant visa operations generally must apply at the designated embassy or consulate for their country, unless they reside elsewhere. Applicants who rely on residence rather than nationality must be able to demonstrate that they reside in the country where they are applying.
Can a third country national apply in Mexico?
It depends on the applicant’s circumstances and the current instructions of the US consular post. A Mexican national may apply in Mexico based on nationality. A person who genuinely resides in Mexico may apply there based on residence, but should be prepared to document that residence and comply with the local post’s appointment and application requirements.
If Mexico is neither the applicant’s country of nationality nor a country where the applicant can demonstrate residence, the applicant should not assume that a US consulate in Mexico will accept the case as a routine third country application. The Department of State advises that applicants who schedule interviews outside their country of nationality or residence, or outside their designated processing post, may find it more difficult to qualify for a visa. The application fee will not be refunded or transferred, and applicants should expect significantly longer appointment waits.
The current Department of State guidance is not worded as an absolute statutory ban on every application made outside the country of nationality or residence. However, it directs applicants to use those locations and warns of practical and adjudication risks when applying elsewhere. A particular embassy or consulate may also have local procedures or appointment restrictions.
Are there exceptions?
The July 2026 Department of State guidance does not apply to applicants for A, G, C-2, C-3, or NATO visas, applicants for diplomatic or official visas regardless of classification, or applicants traveling under the United Nations Headquarters Agreement. The Department of State also states that rare exceptions may be made for humanitarian or medical emergencies or for foreign policy reasons.
Does applying for a visa in Mexico extend US immigration status?
No. A visa stamp and immigration status are different. A visa stamp issued by a US embassy or consulate is generally used to seek admission or reentry to the United States. It does not, by itself, extend a person’s authorized stay inside the United States. A person who needs to extend or change nonimmigrant status while in the United States generally must use the applicable USCIS process and should not rely on a consular visa appointment to preserve status.
Likewise, a person who changed status in the United States through USCIS should not assume that the approval notice is itself a visa stamp for future travel. Before departing the United States to seek a new visa in Mexico or another country, the applicant should review the current status, the approval notice, travel history, any pending applications, and the applicable consular location rules. Limited exceptions to the general visa requirement for reentry may apply in specific circumstances.
Practical steps before making travel plans
- Identify the country of nationality and the country where the applicant can document actual residence.
- Check the Department of State’s current instructions and the website of the specific embassy or consulate where the applicant proposes to apply.
- Review appointment availability, local document requirements, visa fees, and the possibility of administrative processing.
- Consider the consequences of leaving the United States, including the effect on any pending application or current immigration status.
- Do not rely on the 2008 Ciudad Juarez procedure, the former appointment telephone number, or the old list of TCN categories reproduced in the original article.
Scope: This article addresses nonimmigrant visa applications. Immigrant visa interview locations are governed by separate Department of State procedures.
Conclusion
Third country visa processing in Mexico should not be assumed to be available simply because a person can obtain an appointment. Under the Department of State’s July 15, 2026 guidance, nonimmigrant visa applicants should generally apply in their country of nationality or residence, or at the designated processing post where applicable. Applicants who apply elsewhere may face longer waits, nonrefundable fees, and a more difficult visa adjudication. The specific facts and current instructions of the consular post should be reviewed before travel.
