According to the constitution of the Ukraine there shall only be a single form of citizenship. It follows that when a Ukrainian citizen voluntarily acquires a citizenship of another state, he or she loses his or her Ukrainian citizenship. However there are certain other cases – for example, acquiring citizenship by birth – where Ukraine treats dual citizens as if they were Ukrainian citizens only. Ukrainian citizens living abroad have the right to vote.
Due to a controversial amendment in 2010, the current Slovakian legal framework discourages dual citizenship. If a Slovakian citizen voluntarily acquires a citizenship of another state, they automatically lose their Slovakian citizenship. Slovakian citizens residing abroad have the right to vote in general elections.
The Western European nations of France, Spain, Germany, Sweden, Finland, and Portugal make it possible for citizens living abroad to vote in their elections.
Hungary has one of the largest minorities in Europe. There are about 2.2 million Hungarians living outside the borders of Hungary in the neighboring states, and there are likely millions living all over the world. That’s why Hungary remains one of the most proactive kin-states in the region. Hungary amended its law on citizenship in 2010, making it possible for former Hungarian citizens and their descendants to acquire Hungarian citizenship without having to live in Hungary. Before the amendment, dual citizenship was only possible if the applicant moved to Hungary. The amendment now allows those who speak the Hungarian language and are either prior citizens or descendants of Hungarians to apply for citizenship. All those who obtain Hungarian citizenship are eligible to vote in the national elections (regardless of their place of residence). As of the end of 2012, more than 370,000 have applied for Hungarian citizenship, and it is expected that in the next few years this trend will continue.
The law governing the electoral system is still under discussion, but according to the most recent versions, the Hungarian electoral system is a mixed one. Citizens who reside in Hungary have two votes: one for territorial candidates, and one for the national list. Hungarian citizens who do not reside in Hungary may only vote for the national list. Due to the electoral system, analysts say that voters abroad influence only one or at most two of the mandates. In a Parliament of 200 members this may impact the seat count, but it is less likely to change the overall outcome of the elections.
