When we think of state censorship, we often picture prison cells, violent police crackdowns or control of newsrooms. However, our report titled The weaponisation of travel bans to silence speech and dissent published today by Index on Censorship reveals a quieter, less visible tool of state repression that is devastating civil society across the world.
We found that rather than protecting public safety, governments are increasingly manipulating “national security” or “public order” exemptions to trap journalists, fracture families and exile critics. Our research shows that these bans are highly adaptable tools that occur around politically sensitive events such as protests, elections and crackdowns on democratic activity. Their shared, devastating objective is to control narratives, block external scrutiny and create a chilling effect on free expression.
As we researched this topic, we strongly felt that to understand the severity of this crisis, the spotlight must remain entirely on the impacted individuals. The victims of this widespread authoritarian trend pay with their lives and livelihoods being upended by arbitrary and undemocratic measures.
Our analysis highlights that in authoritarian contexts, travel bans act as overt tools of absolute repression. In Saudi Arabia, they function as a form of “quasi-detention”, ensuring that prisoners of conscience remain silenced long after they are physically released from their cells. Take the example of Salma Al-Shehab, a doctoral student at Leeds University, who was imprisoned simply for tweeting in support of women’s rights. Upon her release, she was handed an eight-year travel ban, effectively destroying her academic career by barring her return to the United Kingdom.
Similarly, in Algeria, our research shows how journalists like Mustapha Bendjama find themselves trapped in a bureaucratic nightmare. Extrajudicial travel bans, known as ISTNs, are routinely issued by security agencies without formal judicial oversight, leaving targets in a legal vacuum with no clear avenues for appeal. Bendjama shared with us that this forced isolation acts as a “mental imprisonment” that has dried up his sources and severely compromised his ability to conduct rigorous journalism.
One of our most troubled findings was that the chilling effect of these restrictions extends well beyond authoritarian states, creeping into hybrid democracies. In India, administrative tools like “Look Out Circulars” are deployed to trap critical voices within the country’s borders. Sanna Irshad Mattoo, a Pulitzer Prize-winning photojournalist, was prevented from travelling to New York to accept her award, sending a clear message that international recognition offers no immunity from state retaliation.
In Georgia, foreign journalists who report critically on the country’s democratic backsliding have been arbitrarily denied re-entry at the border using generic legislative clauses. French journalist Clément Giradot was refused entry after reporting on political demonstrations, a decision that suddenly separated him from his home, his Georgian wife and his young child without any concrete legal justification.
It became clear to us that these are not isolated administrative errors. We believe they are part of a coordinated assault on international human rights. Whether it is Nicaragua arbitrarily revoking citizenship to render critics stateless, Belarus forcing exiled dissidents into jeopardy by refusing to renew passports abroad or the United States deploying visa revocations and social media screenings against lawfully present critics, the goal appears to be one: to enforce widespread self-censorship and fear.
The international community can no longer treat these administrative traps as routine border control measures. We urgently recommend taking action. States must do away with these opaque directives, end the use of secondary travel bans as a form of collective punishment against families and align their domestic laws with international human rights standards. Furthermore, democratic host nations must step in to provide secure legal status and alternative travel documents for exiled dissidents while applying sustained diplomatic pressure to demand the lifting of these arbitrary restrictions globally.
Respecting and protecting freedom of speech should not know any ideological boundaries or state borders. With this report, we express our solidarity with the brave ones who raised their voices and with many more who were silenced and never known. While researching and interviewing participants at the front lines of this injustice, we were reminded of the importance of academia’s role as both a sanctuary for freedom of expression and a service to society at large.
