Not in the US military, all commissioned officers by statute must be USA citizens. Has been since, well, ever.
There was a period where duality wasn’t argued, but in 2004 or so, DOD made it the defacto policy. Forswear any and all duality or be separated. I was an ROTC cadre at the time, some wannabees walked, only to find the govt recouping tuition once they quit.
This applies only to a commission in the Regular Army, Navy, etc., as per 10 U.S. Code § 532. It differs for a commission in a reserve component:
§12201. Reserve officers: qualifications for appointment(a)(1) To become an officer of a reserve component a person must be appointed as a Reserve of an armed force in a grade corresponding to a grade authorized for the regular component of the armed force concerned and, except as provided in paragraph (2), subscribe to the oath prescribed by section 3331 of title 5. In addition, to become an officer of the Army National Guard of the United States or the Air National Guard of the United States, he must first be appointed to, and be federally recognized in, the same grade in the Army National Guard or the Air National Guard, as the case may be.
(2) If an officer is transferred from the active-duty list of an armed force to a reserve active-status list of an armed force in accordance with regulations prescribed by the Secretary of Defense, the officer is not required to subscribe to the oath referred to in paragraph (1) in order to qualify for an appointment under that paragraph.
(b) Except as otherwise provided by law, the Secretary concerned shall prescribe physical, mental, moral, professional, and age qualifications for the appointment of persons as Reserves of the armed forces under his jurisdiction. However, no person may be appointed as a Reserve unless he is at least 18 years of age and—
(1) he is a citizen of the United States or has been lawfully admitted to the United States for permanent residence under the Immigration and Nationality Act (8 U.S.C. 1101 et seq.); or
(2) he has previously served in the armed forces or in the National Security Training Corps.
