Help us build the better media Britain deserves
Around the world, a troubling pattern seems to be emerging: governments are increasingly using immigration controls not simply to manage borders, but to suppress political dissent and freedom of expression.
From the United States to Israel, Hong Kong to Nicaragua, the use of visa denials based on political beliefs is fast becoming the favoured tool of exclusion. Politicians, journalists, and students who speak out - particularly in support of Palestinian rights - are facing revocations of status, refusals of entry, and, in some cases, deportation.
In the US, over 300 international students have reportedly had their visas revoked, many from well-known universities such as Columbia, Harvard, and Stanford. These removals are often justified under vague claims of posing a "threat to US foreign policy," a classification that increasingly appears to mean "pro-Palestinian speech".

Mahmoud Khalil, a recent Columbia graduate, had his visa revoked after joining pro-Gaza protests. The revocation, and that of others, draws upon a Cold War-era statute allowing visa cancellations on foreign policy grounds, even in the absence of any criminal wrongdoing.
Another student, Mohsen Mahdawi, a Palestinian-born co-president of Columbia's Palestinian Students Union, was arrested by ICE agents during what should have been his US citizenship interview. And then there is the case of Rasha Alawieh, a Lebanese doctor deported from the US (despite a federal judge's ruling to halt it) for attending the funeral of Hassan Nasrallah, the former leader of Hezbollah.
Meanwhile, progressive Jewish groups and synagogues across the United States have rallied in support of students like Mahdawi, Khalil, and Rumeysa Ozturk - a Tufts University graduate detained after co-authoring an essay critical of Israel. They have condemned the government's actions as both unconstitutional and antithetical to Jewish values, warning of a creeping authoritarianism masked as national security.
Perhaps unsurprisingly, America's actions seemed to have emboldened others. Israel, on April 6, denied British MPs Abtisam Mohamed and Yuan Yang entry while they were attempting to visit the occupied West Bank. The MPs stood accused of planning to spread "hate speech".
In Hong Kong, a similar story unfolds. On 13 April 2025, Liberal Democrat MP Wera Hobhouse was detained for several hours at Hong Kong airport before being deported. Hobhouse, a member of the Inter-Parliamentary Alliance on China (IPAC), has been an outspoken critic of China's human rights record.
'The Free Speech Debate Has a Lot to Do With Race - But the Media Won't Tell You That'
The 'sheer hypocrisy' of the UK's right-wing media in celebrating Trump's 'free speech ultimatum'

These actions, occurring across various nations and to those from the so-called 'Global North' is not - as in the past - against dispossessed and 'unwelcome poor' migrants.
This new turn represents not just the closing of borders but the deliberate exclusion of dissenting voices of power. It's a shift fuelled by counter-narratives that delegitimise truth itself ("journalists/academics can't be trusted") and signals a broader cultural and political move away from a rules-based order and open debate.
In an age where there is a veneered truth that freedom of speech is ubiquitous and ever-present on social media, the state is no lo...
