This comes amid tight laws, strict eligibility, or limited pathways for foreigners.
The list includes:

How is the difficulty of getting citizenship determined?
Residency duration requirements serve as primary difficulty indicators across international citizenship systems. Key criteria include:
Residency Requirements
OECD countries maintain minimum stay requirements ranging from five to twelve years.
Longer residency periods create higher barriers for potential citizens seeking naturalization opportunities.
Countries like Qatar, requiring 25 years, represent extreme examples of extended requirements.
Language Proficiency
The standards significantly impact citizenship acquisition difficulty across different nations worldwide.
Some countries require native-level fluency, while others accept basic communication skills.
Technical vocabulary and formal writing abilities often become mandatory for professional integration.
Cultural context understanding beyond language mechanics frequently receives evaluation during testing procedures.
Financial Criteria
Financial requirements create substantial barriers for citizenship seekers lacking sufficient economic resources.
Income thresholds, employment stability, and tax compliance history undergo comprehensive scrutiny.
Citizenship by Investment programs demonstrate how financial capacity can expedite otherwise lengthy processes.
Economic integration assessments examine the potential contribution to national economic development goals.
Cultural and Social Integration
Cultural integration expectations vary dramatically between countries, emphasizing assimilation versus multiculturalism approaches.
Some nations require extensive knowledge of local customs, history, and political systems.
Others focus primarily on legal compliance and basic social adaptation requirements.
Integration courses and examinations test applicants’ understanding of societal norms and values.
Discretionary approval powers allow governments significant flexibility in citizenship decisions beyond stated requirements.
Administrative authorities can deny applications meeting technical standards for subjective integration concerns.
Political considerations sometimes influence approval rates depending on applicant origin countries.
Bureaucratic processes may extend timelines beyond published estimates through additional scrutiny.
Dual Citizenship Rules
Dual citizenship policies impact difficulty by requiring renunciation of original nationality in restrictive countries.
This creates emotional and practical barriers for applicants maintaining family or business ties.
Countries prohibiting dual citizenship force difficult choices between heritage and new opportunities.
Legal complexities arise when the origin countries don’t recognize renunciation procedures.
