U.S. authorities have revoked the visas of six foreigners who celebrated the assassination of Conservative activist Charlie Kirk on social media.

The State Department announced this move on Tuesday, warning that the U.S. is not obligated to host those who wish its citizens death.

“The United States has no obligation to host foreigners who wish death on Americans. The State Department continues to identify visa holders who celebrated the heinous assassination of Charlie Kirk,” it said. “Here are just a few examples of aliens who are no longer welcome in the U.S.”

The department posted a screenshot of their posts on social media celebrating Mr Kirk’s assassination, saying “visa revoked”.

The six foreigners whose visas were revoked are from South Africa, Brazil, Argentina, Germany, Paraguay, and Mexico.

In a post on X, the department said the Argentinian said in an online post that Mr Kirk “devoted his entire life spreading racist, xenophobic, misogynistic rhetoric” and deserved to burn in hell. Additionally, the department claimed the South African had “mocked Americans grieving the loss of Kirk”, saying “they’re hurt that the racist rally ended in attempted martyrdom” and alleging “he was used to astroturf a movement of white nationalist trailer trash”.

The Brazilian was accused of saying that “Charlie Kirk was the reason for a Nazi rally where they marched in homage to him” and that Kirk “DIED TOO LATE”.

The department alleged that the Mexican said Mr Kirk “died being a racist, he died being a misogynist” and stated that “there are people who deserve to die. There are people who would make the world better off dead”.

While visas of foreigners who celebrated Mr Kirk’s assassination are being revoked, about 145 Americans were fired from work for celebrating the death of Mr Kirk.

Mr Kirk was assassinated at Utah Valley University in September. After his assassination, the U.S. government threatened to revoke the visas of foreigners who celebrated his death.
