Dual citizenship

Swiss legislation allows naturalised persons to have dual citizenship; it is therefore possible for them to retain citizenship of their country of origin.

In some countries, however, voluntary acquisition of Swiss citizenship may lead to the loss of one’s original citizenship if the legislation of the country of origin so provides. For more information, please contact your regional Swiss representation. It should be noted that only official information provided by the authorities of the country of origin can be considered binding.

In the event of enquiries concerning the acquisition of Swiss citizenship, the Swiss authorities are generally obliged to provide information to the foreign authorities.

Please also note the information for dual citizens on military service.
