Nigerian student Owolabi has been meticulously scrubbing his X feed, deleting tweets and comments about United States policies, especially those related to then-President Donald Trump鈥檚 2018 reference to 鈥淸expletive] countries鈥� in Africa.

Mr. Owolabi, got a place at the University of New Haven in Connecticut for a master鈥檚 degree in cybersecurity this year, but with the Trump administration pausing student visa appointments ahead of new social media vetting guidelines, he is worried.

鈥淚 don鈥檛 know what to write on Facebook or X now that won鈥檛 put me in trouble. It feels like someone is watching my every move,鈥� he said.

Mr. Owolabi, who only wanted to be identified by his last name for fear of repercussions, was about to schedule a visa interview at the U.S. embassy in the capital, Abuja, when he heard about the appointment pause for all applicants.

Around 50,000 students from sub-Saharan Africa come to the U.S. every year to study, though China and India send many more.

Around 20,000 Nigerian students went to study at U.S. colleges in 2024 鈥� the highest number from Africa. The United States is a top destination for international students because of the post-degree career opportunities.

In May, U.S. Secretary of State Marco Rubio instructed embassies to stop scheduling new visa appointments, saying the Trump administration would review the process and expand vetting of students鈥� social media profiles.

The directive is part of a broader crackdown on international students with the administration seeking to revoke visas, and increasing deportations of international students.

The U.S. administration has also taken aim at elite universities, notably Harvard. In early June, a federal judge temporarily blocked Trump from barring U.S. entry of foreign nationals seeking to study or participate in exchange programmes at the Ivy League school.

The policies on foreign students are part of a broader immigration crackdown, which the White House says aims to tighten borders and enhance national security.

Unwarranted digital surveillance

Since 2019, most U.S. visa applicants have been required to disclose their social media identifiers, such as their Facebook or X handles.

But Mr. Rubio鈥檚 announcement marks an escalation of the scrutiny applicants will face and raises questions about digital surveillance and the data privacy of applicants, according to digital rights lawyers.

They argue that the level of scrutiny that appears to be under consideration could set a dangerous precedent for digital surveillance in immigration processes.

While details about the new procedures have yet to be revealed, State Department spokesperson Tammy Bruce said the United States was prepared to use 鈥渆very tool鈥� to vet anyone who wanted to enter the country.

Scrutinizing visa applicants鈥� social media activities as part of the immigration process blurs the line between legitimate security concerns and unwarranted digital surveillance, said Khadijah El-Usman, a digital rights lawyer from Paradigm Initiative, a pan-African social enterprise.

Ms. El-Usman said profiling applicants based on their online activity meant innocuous posts on X or Facebook might be misinterpreted, and applicants could be denied visas based on opinions or political jokes.

鈥淲e鈥檝e seen how even social media companies, mostly U.S.-based, misinterpret posts. What this means is that attempts at humor or political critique can be unfairly flagged as security threats,鈥� Ms. El-Usman said.

鈥淐hilling effect鈥�

Digital rights campaigners warned the U.S. move could prompt other countries to normalize digital surveillance as part of immigration processes.

If that happens, all social media users are at risk of being wrongly profiled, said Mojirayo Ogunlana, executive director of Nigeria-based DiGiCiVic Initiative.

鈥淚f someone in a moment of anger says, 鈥榃hy is America supporting Israel?鈥� and they post that on X or Facebook, does that mean they are a terrorist? Or that they are a national security threat? Is that a legitimate reason to deny them visas?鈥� Ms. Ogunlana said.

She said people would increasingly self-censor online by sharing content that aligned with the religious and political ideologies of the U.S. government in case they needed to apply for visas.

This has a 鈥渃hilling effect on freedom of expression鈥� globally, she said, adding that young people, who use social media to express frustrations and draw the world鈥檚 attention to specific causes, will be afraid to do so.

鈥淜nowing that a foreign government might review their tweets or Instagram stories would lead to self-censorship,鈥� Ms. El-Usman said.

鈥淚t encourages the idea that being authentic about your thoughts is risky and forces potential visa applicants and asylum seekers to conform to a government agenda 鈥� the U.S in this case.鈥�

Barbadian student Blackman, who lives in the capital Bridgetown, and also only wanted to give his last name, said he deleted his X and Facebook accounts after receiving an email in May saying his visa application was on administrative hold.

Mr. Blackman, who has been accepted for a master鈥檚 degree in pharmacy at the University of Massachusetts, said classes start in August, but he has yet to hear back about his application.

He has deleted his social media accounts, but is worried about his blog posts in support of the Black Lives Matter movement in the United States, as they are still visible online.

鈥淭he internet gave young people like me a voice to speak about racism and police brutality. Now, I feel silenced and monitored,鈥� Mr. Blackman said.
