MATHIS, Circuit Judge. Benjamin Stanley worked for Western Michigan University (“WMU”) for about one month when WMU terminated his employment. Stanley then sued WMU and a few of its employees. He claimed that WMU and certain supervisors discriminated and retaliated against in violation of the Americans with Disabilities Act (“ADA”). Stanley also brought a claim under Michigan’s Persons with Disabilities Civil Rights Act (“PWDCRA”), as well as a claim for intentional infliction of emotional distress. The district court dismissed Stanley’s federal claims for lack of subject-matter jurisdiction based on Eleventh Amendment immunity and dismissed his state-law claims for failure to comply with the Michigan Court of Claims Act’s notification statute. See Mich. Comp. Laws § 600.6431. The district court also denied leave for Stanley to amend his complaint. We affirm the district court’s dismissal of Stanley’s federal claims and the denial of Stanley’s motion for leave to amend his complaint, but we vacate the judgment in part and remand to the district court to dismiss Stanley’s federal and state-law claims without prejudice.
