NEW YORK (AP) — Mahmoud Khalil, a Palestinian activist and former Columbia University graduate student, has had his latest attempt to dismiss his deportation case rejected by an immigration appeals board. This decision heightens the possibility of his imminent re-arrest and removal from the United States. Khalil expressed disappointment, labeling the ruling as a politically motivated attack on his activism.

On Thursday, the Board of Immigration Appeals rendered its decision, which effectively places Khalil at risk of being expelled from the country while legal battles continue. His legal representatives maintain that Khalil should not be subjected to deportation while challenging the government's actions in federal court.

In a statement, Khalil asserted, “The only thing I am guilty of is speaking out against the genocide in Palestine.” This sentiment underlines the stark reality for many activists who face increased scrutiny and harsh ramifications for their activism.

Khalil, now 31, was detained last year for 104 days, during which he missed the birth of his first child. His case has drawn media attention as it represents broader concerns about the treatment of activists and immigrants who dissent against U.S. policies regarding Israel and Palestine.

Defending his stance, Khalil has insisted that his advocacy for Palestinian rights has not been linked to any extremist groups, despite government claims suggesting otherwise. His lawyers are now urging the full appeals panel to reconsider the recent decision while advocating for fair legal representation.

Khalil's journey began in Syria, where he was born into a Palestinian family. He fears that being deported could result in persecution, and possibly death, given the current geopolitical climate surrounding Palestine. As his legal battles continue, Khalil remains a symbol of resistance amidst fears of political retaliation.
