The U.S. government is once again broadening the scope of its social media vetting apparatus.
On September 18, 2026, the U.S. Department of State announced that its existing online presence review will expand to applicants in the TN, TD, and I nonimmigrant visa classifications beginning October 1, 2026.
The move marks the latest phase in a multi-year effort to subject an ever-widening pool of visa applicants to digital scrutiny — and it carries significant practical implications for Canadian and Mexican professionals, their families, and foreign journalists seeking entry to the United States.
Who Is Affected?
Beginning October 1, 2026, the U.S. Department of State will expand its online-presence review to applicants for three additional nonimmigrant visa classifications: TN visas for qualifying Canadian and Mexican professionals under the United States-Mexico-Canada Agreement (USMCA); TD visas for qualifying dependents of TN professionals; and I visas for representatives of foreign media.
The TN visa job list contains exactly 63 professional occupations approved under the USMCA
,
supporting expedited entry for eligible professionals in fields such as engineering, law, science, education, and healthcare.
With streamlined processing and no annual cap, the TN visa offers a practical route for cross-border workforce mobility.
The I visa category covers foreign journalists, broadcasters, and other media representatives accredited to operate in the United States — a population with particular First Amendment and press freedom implications.
What Applicants Must Do
As part of the enhanced vetting process, applicants in these categories are instructed to set all social media accounts and profiles to "public" or "open" so that consular officers can review available online content during the visa adjudication process.
This requirement is distinct from the longstanding obligation to disclose social media identifiers on the DS-160 visa application form.
Since 2019, the Department of State has requested social media identifiers from most immigrant and nonimmigrant visa applicants as part of the visa application process.
Since 2019 the DS-160 has asked every applicant to list the social media identifiers they have used in the previous five years, and it sits in the Address and Phone section of the form.
What changes on October 1 goes further:
TN, TD, and I visa applicants are being added to the categories subject to the Department's expanded online-presence review
— meaning consular officers will actively examine the content of applicants' social media profiles rather than simply collecting account names.
Applicants whose cases remain pending on October 1 should prepare for the expanded review, even if they submitted their applications or scheduled interviews earlier.
Building on a Pattern of Expansion
This announcement is not occurring in a vacuum.
The State Department first expanded online presence review to F, M, and J visa applicants (students and exchange visitors) in June 2025, and later added H-1B workers and their H-4 dependents in December 2025.
The March 30, 2026 expansion was the third — and largest — to date, adding 14 additional visa categories
,
including K-1, K-2, K-3, R-1, R-2, H-3, A-3, C-3, G-5, Q, S, T, and U visa applicants.
The expansion adds these classifications to the growing list of visa categories subject to enhanced screening and vetting during consular visa adjudications.
The October 1 addition of TN, TD, and I visas represents the fourth wave of expansion in roughly 16 months.
Processing Delays: The 221(g) Factor
Perhaps the most consequential practical concern for applicants is the potential for processing delays.
For those applications subject to online presence review, additional administrative processing may affect visa issuance timelines.
While consulates often continue processing visas regardless of privacy settings, employers and foreign nationals should be aware of this development and watch for emerging trends, such as 221(g) notices tied to social media reviews.
A 221(g) notice is a procedural hold — not a denial — but it can significantly disrupt travel and work plans.
It indicates that the visa application is on hold, typically due to incomplete documentation or the requirement for additional administrative review.
Visa turnaround can take up to a month if not longer, including administrative processing, printing, and shipping.
When the Department of State rolled out social media screening for F and J visa applicants in 2025,
one of the biggest changes was that all F or J visa applicants who after interviewing were eligible for the visa would now have their visa "refused" due to 221(g) for additional administrative processing while the applicant sets their social media accounts to "public" and the consular officials perform a thorough review.
There is reason to expect a similar pattern for TN, TD, and I applicants.
According to the U.S. Department of State, approximately 17% of all visa applications received 221(g) status in 2024.
In 2025, preliminary data indicate that the proportion of 221(g) cases has increased to 19% due to increased screening, including analysis of social media activity.
Special Considerations for Canadian TN Applicants
The screening expansion raises unique questions for Canadian citizens.
Canadian citizens residing outside the United States are not required to apply for a TN visa at a U.S. consulate.
Many Canadians obtain TN status directly at a U.S. port of entry or pre-flight inspection site, bypassing the consular interview process entirely.
For Canadians who rely on TN status to work in the United States, this represents an important change in the U.S. government's approach to screening TN and TD visa applicants.
However, the social media screening requirement as announced specifically applies to the consular visa adjudication process. Whether and how CBP officers at ports of entry will implement similar reviews remains to be seen.
Mexican TN applicants, who generally must apply for a TN visa at a U.S. consulate, will be directly and immediately affected by the new requirement.
What Applicants Should Do Now
Individuals with TN, TD, or I visa interviews scheduled on or after October 1, 2026 should take several proactive steps:
1. Review all social media profiles across every platform and set privacy settings to "public" or "open" before the consular interview.
2. Audit social media content for anything that could be misinterpreted or raise concerns during the vetting process.
3. Ensure DS-160 accuracy —
omitting an account you actually used is treated as a misrepresentation risk, not a rounding error.
4. Do not delete accounts —
applicants should follow official guidance and provide accurate information; deleting accounts is not listed as a general requirement.
5. Build in extra time for potential administrative processing delays, particularly if travel or employment start dates are time-sensitive.
Employers and affected applicants should review upcoming consular appointments and travel plans now and prepare for the public-profile requirement described in the September 18 announcement.
The Bigger Picture
The government says it uses available sources of information during visa screening to determine applicants' eligibility and identify potential national security or public safety concerns.
The State Department has consistently framed these expansions as necessary security measures.
Yet critics have long raised concerns about the chilling effect on free expression. When the DS-160 social media question was first introduced in 2019,
the ACLU commented that the requirement would "infringe on the rights of immigrants and U.S. citizens by chilling freedom of speech and association, particularly because people will now have to wonder if what they say online will be misconstrued or misunderstood by a government official."
The extension of enhanced social media review to I visa applicants — foreign journalists and media representatives — could amplify these concerns, given the press freedom implications inherent in government review of media professionals' online activity.
As the Department of State continues to broaden the universe of visa categories subject to social media screening, applicants and their employers should expect that this trend will persist. Consulting with an experienced immigration attorney before a consular appointment is increasingly advisable to navigate the evolving vetting landscape.
