When you're here for school are you considered a MI resident? If so your out of state permits won't do anything for you (see AG opinion below). If you are NOT a MI resident while you're here for school then I'd say yes you could OC with your out of state permits under the same rules as a MI resident that does NOT have a CPL, i.e., no vehicle carry, no carry on premises of establishments licensed to sell alcohol, etc.
MCL 28.432 allows a non-MI resident to use their out of state concealed license in lieu of having to get Permits to Purchase/Possess and register their guns, since only MI residents may do so.
Here's an AG opinion that deals somewhat with this issue. It is really about whether or not a MI resident may conceal carry with only an out of state concealed license. I think the state would apply what the AG wrote in the last paragraph for your scenario.28.432 Inapplicability of MCL 28.422; amendatory act as “Janet Kukuk act”.
(1) Section 2 (is the License to Purchase/Possess law) does not apply to any of the following:
(f) A United States citizen holding a license to carry a pistol concealed upon his or her person issued by another state.
So (this is all just my opinion, ask a lawyer...which I'm not) if you are NOT a MI resident you may use your non MI concealed license in place of getting Licenses to Purchase/Possess and register your guns. You are then bound by the same laws regarding carry as a MI resident that does NOT have a CPL.Here, the Legislature has created local gun boards with the exclusive authority to issue concealed pistol licenses. The Legislature has imposed specific statutory requirements applicants must meet to obtain these licenses. In addition, whether applicants have good reasons and are suitable persons to be licensed is within the sound discretion of a board of local professionals who apply their knowledge of community needs and problems in evaluating applications. It is inconceivable that the Legislature, after crafting these statutory requirements for obtaining a concealed pistol license, intended to permit Michigan residents to avoid them by obtaining a concealed pistol license in another state that may not impose many of the Michigan requirements. That construction of the statute would result in the absurd consequence that a Michigan resident could avoid the legislatively imposed requirements for obtaining a concealed pistol license in Michigan by obtaining that type of license in another state without having to meet the Michigan requirements. Thus, it must be concluded that a Michigan resident with a concealed pistol license obtained in another state may not carry a concealed pistol in Michigan unless the resident first obtains a concealed pistol license in Michigan by meeting the requirements for obtaining the license imposed by Michigan law.
