Summary (tl;dr)

Nationality law is trending due to significant reforms in Germany making citizenship acquisition easier, recent changes in Portugal that extend the timeline for naturalization, and ongoing legal challenges in the United States concerning birthright citizenship and green card processes.

Essential Background

Historically, many countries have had strict nationality laws, often requiring individuals to renounce previous citizenships upon naturalization and imposing lengthy residency requirements. In the United States, birthright citizenship, based on the 14th Amendment, has been a long-standing principle, granting citizenship to nearly all individuals born on U.S. soil. Portugal has been a popular destination for investment migration, with a relatively quick pathway to citizenship.

The Full Story

"Nationality law" is currently trending due to several significant developments across different nations. In Germany, the Act to Modernise Nationality Law (StARModG) officially entered into force on June 27, 2024. This new legislation permits individuals to hold multiple citizenships, reduces the minimum residency period required for naturalization from eight to five years (or even three years in cases of exceptional integration), and simplifies the process for foreign children born in Germany to acquire citizenship. These changes aim to attract skilled workers and promote integration, generating considerable discussion as individuals explore their new eligibility.

Meanwhile, in Portugal, President António José Seguro promulgated a revised Nationality Law on May 3, 2026, marking one of the most substantial changes to the country's citizenship framework in decades. The reform extends the standard legal residence requirement for naturalization from five years to 10 years for most foreign nationals, while EU citizens and those from Portuguese-speaking countries will face a seven-year requirement. Crucially, the new law also dictates that the qualifying residence period now begins from the date a valid residence card is issued, rather than the application date, which, given existing processing delays at Portugal's migration agency (AIMA), could significantly prolong the practical timeline to citizenship.

In the United States, the Supreme Court is expected to deliver rulings by the end of June 2026 on major cases concerning birthright citizenship, specifically addressing a former executive order that sought to end it for children born to parents residing in the U.S. illegally or temporarily. This potential decision could upend over a century of legal understanding. Additionally, new administrative policies are impacting green card applicants, with U.S. Citizenship and Immigration Services (USCIS) requiring some foreign nationals temporarily in the U.S. to return to their home countries to apply for permanent residency, except in extraordinary circumstances. USCIS is also increasing scrutiny on continuous residence, tax compliance, and overall "good moral character" for naturalization applications, leading to longer adjudication times and more requests for evidence.

Why It Matters

The changes in Germany are significant as they represent a more inclusive approach to nationality, aiming to make the country more attractive for foreign talent and better integrate long-term residents. This shift acknowledges the reality of a diverse society and allows individuals to maintain ties to their country of origin while fully participating in German society.

The revised law in Portugal has profound implications, particularly for investors participating in programs like the Golden Visa. The extended naturalization timeline and the altered method of calculating residency are creating uncertainty and may deter some foreign residents and investors who sought Portuguese citizenship as a quicker pathway to EU benefits. This could impact Portugal's attractiveness in the global investment migration market.

In the United States, the impending Supreme Court decision on birthright citizenship carries immense weight, as it could fundamentally redefine who is considered a U.S. citizen and reshape immigration policy for generations. Coupled with stricter administrative policies on green card and naturalization applications, these developments signal a tightening of immigration pathways and heightened scrutiny for those seeking permanent residency or citizenship in the U.S.
