International mobility is a coveted asset in contemporary times. A second passport can open doors to another country, providing various financial, cultural benefits, and freedom. Especially during times of uncertainty and unforeseen catastrophes, it can serve as a vital alternative security plan. A dual/multiple citizen is someone who holds legal citizenship in two countries simultaneously. This status entails both rights (such as passport issuance, entry into the country, work, and residence) and obligations (taxation, national duty, etc.). For a detailed analysis, please refer to our article on Dual Citizenship: Advantages, Disadvantages, and Requirements.

The concept of dual nationality has undergone significant changes over the years. Once considered alien, it is now openly and widely discussed, particularly since the end of the Cold War, marking an era where a more liberal approach towards dual citizenship began to emerge. This shift is attributed, in part, to greater gender equality and the abandonment of mandatory military service. The connection to gender equality is argued through the discriminatory act of women having to relinquish their nationality after marriage for their husband’s, causing related problems. The UN Declaration of Human Rights underscores everyone’s right to nationality, emphasizing its fundamental nature in the global discourse on citizenship.

Why Covet European Nationality?

Europe, being one of the largest destinations for immigrants, welcomed 86.7 million international immigrants in 2020. Holding an EU citizenship comes with numerous advantages. Being a citizen of any of the 27 EU member states automatically grants EU citizenship, facilitating work and residence in another EU state without the need for a visa or additional permits. Consequently, it is not surprising that in 2021, 827,300 people acquired EU citizenship, with 85% of them transitioning from non-EU countries to enjoy the benefits that come with EU citizenship.

European Attitude Towards Dual Citizenship

According to The Macimide Global Expatriate Dual Citizenship Database, the European Union has witnessed a notable shift in policies regarding dual citizenship. The percentage of countries automatically revoking citizenship upon acquisition of another has decreased from 63% in 1960 to 24% in 2020, signaling an increasing tolerance for dual citizenship. Despite this trend, specific countries such as Austria, Germany, Estonia, Bulgaria, Spain, Latvia, Lithuania, and the Netherlands remain hesitant to permit dual citizenship, enforcing strict rules for exceptions.

Global Players in the European Market

The European market is expanding by attracting a diverse range of immigrants through its acceptance of dual citizenship and various citizenship programs. This growth is evident in the presence of various multinational corporations operating in the market, such as ASML Holding N.V. (NASDAQ: ASML) and AstraZeneca plc (NYSE: AZN). The appeal of dual citizenship not only contributes to demographic diversity but also fosters economic development by drawing in skilled professionals and entrepreneurs. This intersection of diverse immigration policies and a flourishing corporate landscape underscores Europe's attractiveness as a global destination for both individuals and businesses alike.


ASML Holding N.V. (NASDAQ: ASML), a Dutch multinational company, stands out as a pivotal player with a profound impact on the flourishing tech world. The company has earned a significant reputation in the industry, being recognized as Europe's AI champion and hailed as "the continent’s most valuable tech firm." ASML Holding N.V.'s contributions are evidently crucial to the advancements in technology, and their prominence underscores their noteworthy role in shaping the landscape of the tech industry in Europe and globally.

AstraZeneca plc (NYSE: AZN) stands as another prominent global firm, albeit in a different industry. As a pharmaceutical giant, the company is characterized by continuous innovation and sustained growth. Notably, at the close of the previous year, AstraZeneca plc (NYSE: AZN) made headlines by expressing their intent to acquire their first vaccine company, signaling a strategic move to expand their business portfolio.
