10 countries where getting citizenship is difficult for Nigerians, others

Securing citizenship in a foreign country can unlock greater security, mobility, and long-term opportunities for millions worldwide. However, the path to naturalization varies dramatically, with some nations presenting significant hurdles.

Qatar, for instance, operates one of the world's most restrictive systems, demanding 25 years of residency, Arabic proficiency, and good conduct, with final approval remaining tightly controlled. Vatican City offers a unique model, granting citizenship based on specific roles within the Holy See, which ends when the position does, rather than traditional residency.

Liechtenstein requires decades of residence and can involve complex local and national approval procedures, making it a highly selective process. Bhutan prioritizes its national identity with demanding residency, cultural, and integration requirements, subject to government scrutiny. Saudi Arabia favors family heritage for citizenship but offers limited pathways for highly skilled professionals, still with stringent government approval.

Kuwait maintains strict controls, restricting naturalization to specific categories and often involving lengthy residency. Switzerland combines federal, cantonal, and municipal requirements, typically needing around 10 years of residence. These examples highlight the diverse and often challenging landscapes foreigners face when seeking a new nationality.
