WASHINGTON (VINnews) — A federal immigration appeals board has denied an effort by activist Mahmoud Khalil to dismiss his deportation case, advancing proceedings that could lead to his removal from the United States, his attorneys said according to the NY Post.

The Board of Immigration Appeals issued the ruling, allowing the case to move forward within the immigration system. Khalil’s legal team said he will continue to challenge the decision in federal court.

Khalil, a lawful permanent resident and former student at Columbia University, has argued the case is politically motivated and tied to his activism related to the Israel-Gaza conflict.

U.S. officials have raised concerns about his activities, while his attorneys say there is no evidence linking him to any terrorist group. Khalil has denied allegations of antisemitism.

He has said he fears for his safety if deported.
