Art. 3 Ordinance of November 22, 2017, on Military Obligations (OMO) - Dual Nationals
Art. 3 OMi · Dual Nationals
Swiss nationals residing in Switzerland who hold the nationality of another state (dual nationals) and who have fulfilled their military obligations or alternative service in that other state before taking up residence in Switzerland, or due to an international agreement between Switzerland and that state on the mutual recognition of the completion of military service by dual nationals, must report this to the district commander.
Dual nationals remain subject to military service in Switzerland if: a. the report as referred to in paragraph 1 has not been made; b. it cannot be proven that the service was completed in the other state; or c. the services completed are not at least equivalent to those required in Switzerland.
The Instruction Command (cdmt Instr) makes a decision in these cases.
