奥羽本線の線路にそって人ひとりがやっと通れる道があった。危険なので地元は道の拡幅を望んでいた。アジア太平洋戦争の末期、そこて道路工事が始まった。記録は朝鮮人と地元の子どもたちの交流を、当時国民学校に通っていた地元の人たちから聞き取って紹介している❓(大野和興)

令和7年春の褒章（消防関係）（令和7年4月28日）

　それでは2017年～21年の第1次トランプ政権の時はどうだったのか。やはり福音派の意向に沿い政策を実行した。つまりパレスチナ切り捨てだった。安保理決議を覆す　そもそもイスラエルのパレスチナ国家占領に対し、米政府は基本的に１９６７年の安保理決議２４２号（占領地からの撤退勧告）支持する姿勢を維持していてきたが、トランプ政権はこれを覆した。占領承認と難民保護政策からの撤退へと舵を切り替えた。さらに国連パレスチナ難民救済事業機関（UNRWA）を脱退し、難民支援から手を引いてしまった..

南海岸にある浜辺の村アミオ村には、かつてSBLCが内陸部で伐採した木材を海外へ積み出していた作業所と桟橋があった。しかし、SBLCは２００３年に撤退し、桟橋はそのまま朽ち果て、作業所と機材は打ち捨てられたまま今でも草に埋もれている。

　トランプ米政権は、リベラル系の大学への締め付けを強化し、それに抗うなら助成金の取り消しなどの措置で圧力をかけている。　著名なエリートを輩出している名門ハーバード大への介入はその代表例だ。反ユダヤ主義的な活動やDEI（多様性、公平性、包摂性）の見直しを拒否した同大への助成金２２億ドル（約３１００億円）と６０００万ドル（約５６億円）相当の契約金の支払いを凍結した。さらにトランプはハーバード大が今後も「テロリストを支援するような『病的』な行動を押し進めるなら、免税資格措置を剥奪し..

The federal government is using social media surveillance to target student visa holders living in the United States for online speech the Trump administration disfavors. The administration has initiated this new program, called “Catch and Revoke,” in an effort to revoke visas, and it appears to be a cross-agency collaboration between the State Department, the Department of Homeland Security (DHS), and the Department of Justice. It includes a dedicated task force and the use of AI and other data analytic tools to review the public social media accounts of tens of thousands of student visa holders. Though the full scope remains unclear, current reports indicate that the administration is surveilling for “pro-Hamas” sentiment, “antisemitic activity,” or even just “conduct that bears a hostile attitude toward U.S. citizens or U.S. culture.” At the time of publishing of this blog post, the federal government has already revoked over 1600 student visas for a variety of reasons.

This social media surveillance program is an alarming attack on freedom of speech and privacy—for both visa holders here in the United States and their American associates.

A Dangerous Erosion of Free Speech

While there is some nuance in the interplay between freedom of speech and immigration law, one principle is evident: foreign nationals who currently reside in the U.S.—including student visa holders—are protected by the First Amendment. The Supreme Court stated in Bridges v. Wixon (1945) that “[f]reedom of speech and of press is accorded aliens residing in this country.”

First Amendment-Protected Political Speech

Revoking student visas based, in part, on what students have said publicly on social media is especially constitutionally problematic given that the Trump administration is targeting core First Amendment-protected political speech. As the Supreme Court stated in Mills v. Alabama (1966), a central purpose of the First Amendment is to “protect the free discussion of governmental affairs,” whether on political issues, public officials, or how the government should operate.

The administration is targeting non-citizen students for “pro-Hamas,” antisemitic, and even just pro-Palestinian speech. Yet what falls under these categories is vague and not clearly defined. For example, the administration detained a Georgetown University researcher due to social media posts that are critical of Israel, but do not express support for Hamas.

More importantly, even controversial or offensive speech falls within the protections of the First Amendment. There are several categories of speech that do not enjoy First Amendment protection, including true threats of violence, inciting imminent violence, and providing material support for terrorism. However, short of rising to that level, the student speech targeted by the administration is protected by the First Amendment. Worse still, the administration is broadly going after students who simply appear to be “social activists” or are engaged in speech that is generically “anti-American.”

Such an overbroad social media surveillance and visa revocation program—one that sweeps in wholly lawful speech—strikes at the heart of what the First Amendment was intended to protect against.

Chilling Effect

Social media surveillance motivated by the government’s desire to punish political speech will chill (and certainly has already chilled) student visa holders from speaking out online.

The Supreme Court stated in Lamont v. Postmaster General (1965) that a government policy that causes individuals “to feel some inhibition” in freely expressing themselves “is at war with the ‘uninhibited, robust, and wide-open’ debate and discussion that are contemplated by the First Amendment.” More recently, Supreme Court Justice Sotomayor expressed in a concurring opinion that “[a]wareness that the Government may be watching chills associational and expressive freedoms” guaranteed by the First Amendment.

In other words, student visa holders are more likely to engage in self-censorship and refrain from expressing dissenting or controversial political views when they know they're being surveilled. Or they may choose to disengage from social media entirely, to avoid the risk that even seemingly harmless posts will affect their visa status and their ability to continue their education in the United States.

Student visa holders may also limit whom they connect with on social media, particularly if they fear those connections will have political views the current administration doesn’t like. The administration has not expressly stated that it will limit its surveillance only to the social media posts of student visa holders, which means it may also look at posts made by those in the students’ networks. This, too, undermines the First Amendment. The freedom to associate and express political views as a group—“particularly controversial ones”—is a fundamental aspect of freedom of speech, as the Supreme Court stated in its landmark NAACP v. Alabama (1958) decision.

American Citizens Impacted

Because student visa holders’ social networks undoubtedly include U.S. citizens, those citizens may also be subject to social media scrutiny, and therefore will also be chilled from freely speaking or associating online. Government agents have previously held visa holders responsible for the activity of their social media connections. Knowing this, a U.S. citizen who has a non-citizen friend or family member in the U.S. on a student visa might hesitate to post criticisms of the government—even if fully protected by the First Amendment—fearing the posts could negatively impact their loved one. A general climate of government surveillance may also lead U.S. citizens to self-censor on social media, even without any foreign national friends or family.

A Threat to Digital Privacy

Social media surveillance, even of publicly available profiles and especially with automated tools, can invade personal privacy. The Supreme Court has repeatedly held that the government’s collection and aggregation of publicly available personal information—particularly when enhanced by technology—can implicate privacy interests. The government can obtain personal information it otherwise would not have access to or that would usually be difficult to find across disparate locations.

Social media aggregates personal information in one place, including some of the most intimate details of our lives, such as our health information, likes and dislikes, political views and religious beliefs, and people with whom we associate. And automated tools can easily search for and help find this information. Even people who choose not to post much personal information on social media might still be exposed by comments and tags made by other users.

Constitutional Harms are Exacerbated by Automated Tools

The Trump administration is reportedly deploying artificial intelligence and other automated tools to assist in its review of student visa holders’ social media posts. While facts are still coming to light, any form of automation is likely to amplify speech and privacy harms to student visa holders.

By the government’s own assessment in another context—evaluating the admissibility of visa applicants (discussed below)—social media surveillance has not proven effective at assessing security threats.

Human review of public social media posts is itself prone to problems. Social media posts are highly context-specific, and government officials often have trouble differentiating between sarcasm, parody, and exaggeration from unlawful support for controversial causes. This leads to mistakes and misinterpretations. For example, in 2012 an Irish citizen was turned back at the border because DHS agents misinterpreted two of his Twitter posts: one, that he was going to “destroy America” – slang for partying – and two, that he was going to “dig up Marilyn Monroe’s grave” – a joke. These mistakes are even more likely when the posts are not in English or when they contain cultural references .

Human review augmented by automated tools is just as bad. Automated tools also have difficulty understanding the nuances of language, as well as the broader context in which a statement was made. These algorithms are also designed to replicate patterns in existing datasets, but if the data is biased, the technology simply reinforces those biases. As such, automated tools are similarly prone to mistakes and misinterpretations. Yet people often defer to automated outputs thinking they are correct or fair simply because a computer was used to produce them. And in some cases, decision-makers may even use these tools to justify or cover their own biases.

Most concerning would be if automated systems were permitted to make final visa revocation decisions without any human review. As EFF has repeatedly stated, automated tools should never get the final say on whether a person should be policed, arrested, denied freedom, or, in this case, stripped of a student visa and forcibly barred from completing their education.

Government Social Media Surveillance is Not New—and is Expanding

That the Trump administration is using social media surveillance on student visa holders residing in the United States is a disturbing apparent escalation of a longstanding trend.

EFF has long sounded the alarm on the civil liberty harms of government social media surveillance. In particular, since 2019, visa applicants have been required to disclose all social media accounts they have used in the last five years to the U.S. government. That policy is the subject of an ongoing lawsuit, Doc Society v. Pompeo, in which EFF filed an amicus brief.

Secretary of State Marco Rubio recently upped the ante by ordering officials to deny visas to new or returning student applicants if their social media broadly demonstrates “a hostile attitude toward U.S. citizens or U.S. culture (including government, institutions, or founding principles).” Notably, Rubio indicated this standard could also apply to current student visa holders. The State Department also announced it will review the social media of any visa applicant who has been to Gaza since 2007.

The Trump administration has also proposed dramatically expanding social media scrutiny by requiring non-citizens already legally residing in the U.S. to disclose social media accounts on a variety of forms related to immigration benefits, such as people seeking lawful permanent residency or naturalization. U.S. Citizenship and Immigration Services (USCIS), a component of DHS, also announced it would look for “antisemitic activity” on social media to deny immigration benefits to individuals currently in the country.

Protecting Your Accounts

There are general steps you can take to better protect your social media accounts from surveillance. Understand, however, that the landscape is shifting rapidly and not all protections are foolproof. Law enforcement may be able to get a warrant for your private information and messages if a judge is convinced there is preliminary evidence supporting probable cause of criminal activity. And non-governmental individuals and groups have recently used other forms of technology like face recognition to identify and report student activists for potential deportation. You should conduct your own individualized risk assessment to determine what online activity is safe for you.

Still, it never hurts to better secure your online privacy. For your current social media accounts, consider locking them down:

• Make public accounts private and ensure only approved connections can see your content. Note that if your past public posts have already been copied and saved by an outside party, making your account private will not undo this. It will, however, better protect your future posts.
• Some platforms make certain information publicly viewable, even if you’ve made your account private. Other information may be public by default, but can be made private. Review each platform’s privacy settings to limit what information is shared publicly, including friend lists, contact information, and location information.
• You should also review your friends or followers list to ensure you know every person you’ve approved, especially when making a once-public account private.

If you create a new social media account:

• Query whether you want to attach your legal name to it. Many platforms allow you to have a pseudonymous account.
• When setting up the account, don’t provide more personal information than is necessary.

EFF’s Surveillance Self-Defense guide provides additional information on protecting your social media accounts from a variety of actors. If you're not sure what information is publicly available about you on social networks or other sites, consider doing some research to see what, if anything, others would find.

By targeting international students for broad categories of online speech, this administration is fostering a climate of fear, making students anxious that a single post or errant “like” could cost them their U.S. visa or even lead to detention and deportation. This will, ultimately, stifle political debate and silence dissent–for non-citizens and citizens alike–undermining the open dialogue crucial to democracy.
