Can a foreigner obtain Swiss citizenship by virtue of same-sex registered partnership with citizen Switzerland?

No, a foreigner cannot obtain Swiss citizenship by virtue of a same-sex registered partnership with a citizen of Switzerland. However, a foreigner may obtain Swiss citizenship if he or she is married to a Swiss citizen and meets certain other requirements, such as residency in Switzerland for a certain number of years. Additionally, a minor child born to a Swiss parent and a foreign parent may automatically become a Swiss citizen.
