Sworn Elsewhere
On 7 August, Colombia's president-elect, Abelardo de la Espriella, takes office. He will swear to keep faith with the Constitution and take command of the armed forces. Yet he has already sworn, in an oath that remains formally operative, to renounce all allegiance to every other sovereign and to bear arms for the United States. Constitutions that make dual nationality an individual right seldom pause to ask what that right means for the one office meant to personify the sovereignty of the people. Colombia can no longer avoid the question. Continue reading >>

Neither Soil, Nor Blood, Nor Money
Russian oligarchs in Malta, descendants of Italians in South America, and Mexicans crossing into the US make unlikely characters for a common story. Yet over the first half of 2025, the ability of each of these groups to acquire or transmit citizenship status has been under scrutiny, signalling a shared preoccupation with ensuring that citizenship reflects “authentic” bonds and is not acquired instrumentally. In the struggle to define these “authentic” bonds each intervention strikes at the heart of some well-known citizenship tenet – the link to soil, blood, or money – without offering a clear alternative. The resulting void calls for a reflection on the principles that ought to inform rules on citizenship attribution. Continue reading >>06 December 2022
Upgrading German Citizenship
As part of their broader agenda to “modernize” its immigration laws, Germany’s government has proposed to ease immigrants’ access to citizenship. The opposition – especially the CDU – as well as the liberal government coalition partner FDP are not happy with this. Among other things, they are concerned that the new law would seriously diminish the value of German citizenship and insist that immigrants should successfully integrate before they become German nationals. I argue in the following that these concerns, and further claims, are unfounded. Continue reading >>05 April 2017
More Is Less: Multiple Citizenship, Political Participation, and Mr Erdogan
I must differ with my colleague, Peter Spiro, and those who consider dual citizenship unproblematic or even progressive and a facilitator of immigrant integration. The devaluation of citizenship that widespread dual citizenship both reflects and worsens is in fact bad for those who need democracy and seek social equality. It is also another moment in which political power has yielded to market power. At the same time, making dual citizenship illegal, or even discouraging it, is a pointless effort since even after the current nationalist-populist wave passes, human mobility is highly likely to remain at high levels.

Germany and the Erdogan Referendum: the Case for External Voting and Dual Citizenship
Almost a million and a half Turkish citizens resident in Germany are eligible to cast absentee ballots in a Turkish referendum to scrap its parliamentary system. The run-up to the referendum had German authorities obstructing pro-Erdogan rallies, to which Erdogan himself responded with charges that the German government was engaging in “Nazi practices.” The episode marks perhaps the most prominent and controversial example of external political campaigning since such activity has become normalized among states.
