NEW YORK (AP) — An immigration appeals board has denied Mahmoud Khalil’s latest bid to dismiss his deportation case, a ruling that brings the former Columbia University graduate student and Palestinian activist one step closer to re-arrest and possible expulsion.

The Board of Immigration Appeals issued the final order of removal on Thursday. Khalil called the ruling biased and politically motivated and highlighted that he cannot be lawfully detained or deported while pursuing a separate case in federal court.

“The only thing I am guilty of is speaking out against the genocide in Palestine — and this administration has weaponized the immigration system to punish me for it,” Khalil stated.

The board's rulings are not public, and inquiries to the U.S. Department of Justice have yielded no immediate response.

Amid increasing scrutiny, the board that sets precedent within the complex immigration court system has come under suspicion for bias, particularly under the Trump administration's influence. Khalil, a 31-year-old legal permanent resident, became known after being arrested during the federal crackdown on non-citizens openly criticizing Israeli actions.

The government has alleged connections between Khalil's activism and Hamas, a charge he vehemently denies, claiming no evidence has been presented for such assertions.

Last year, Khalil spent 104 days in immigration detention, during which he missed the birth of his first child. He was subsequently released by a New Jersey federal judge, only for a U.S. appeals panel to later reverse that decision, stating it should go through immigration courts first.

Khalil's lawyers are currently challenging the ruling and have requested a full appeals panel to reconsider the panel’s decision while raising concerns over potential biases from one of its judges due to prior Justice Department roles.

Born in Syria to a Palestinian family and holding Algerian citizenship, Khalil has expressed concerns about facing severe repercussions, including death, if deported.
