Factors That Make Citizenship Hard to Get

When we say a country is one of the hardest countries to get citizenship in 2025, we look at several key factors:

  1. Length of Residency: The longer you need to stay before applying, the harder it becomes.
  2. Language and Culture Tests: Mastering a new language and adapting to local customs is not easy.
  3. Dual Citizenship Policy: Countries that don’t allow dual citizenship force applicants to give up their original nationality.
  4. Government Discretion: In places like UAE or Qatar, citizenship is given based on the government’s decision, not standard criteria.
  5. Public Opinion: In countries like Switzerland, local citizens can block applications.

Final Thoughts

For many, becoming a citizen of another country is a dream—whether for better opportunities, safety, or a new life. However, for the countries listed above, that dream is far from easy to achieve. From strict residency requirements to cultural expectations, these nations have built strong barriers to entry.

As of 2025, the global landscape shows that immigration policies are tightening, not relaxing, making it even more challenging. Whether you are planning to apply or are just curious, knowing which are the hardest countries to get citizenship in 2025 can help set realistic expectations.
