Passport ≠ Citizenship
Every known case worldwide where a passport or travel document can be held without full citizenship rights. 18 exceptions across 7 categories.
In the vast majority of cases, a passport = citizenship. The exceptions below are edge cases rooted in colonial history, employment law, territorial status, and international refugee law. For the citizenship pathways covered in this guide (Malta, Portugal, Albania, Vietnam, etc.), the passport issued reflects genuine, full citizenship.
Understanding the passport ≠ citizenship distinction matters for two reasons. First, it clarifies what you are actually acquiring when you pursue a second passport programme. The Malta Startup Residence, Paraguay naturalization, and Albania residency routes all lead to full citizenship — not the partial, employment-dependent, or historically-contingent statuses documented below. You will hold the same legal status as someone born in that country.
Second, the exceptions below reveal how citizenship law actually works at its edges. The SMOM case demonstrates that sovereignty can exist without territory. The Vatican case demonstrates that citizenship can be a temporary employment benefit. The American Samoa case demonstrates that the US Constitution's citizenship guarantee does not automatically extend to all US territories. These are not academic curiosities — they are the legal mechanisms that make the entire second passport industry possible.
British Nationality Sub-Tiers
British National (Overseas) — BN(O)
Born in Hong Kong before 1997 handover and registered before 1997
No automatic right to live/work in UK (2021 visa route partially changed this)
Yes — full British passport
Inherited — closed to new applicants since 1997
British Overseas Citizen (BOC)
Held CUKC status in former colonies at independence
No right to live/work in UK, non-transmissible (cannot pass to children)
Yes — British passport
Inherited — essentially closed to new applicants
British Overseas Territories Citizen (BOTC)
Born or naturalized in a British Overseas Territory
No right to live in UK itself (unless also a British Citizen)
Yes — British passport
Ongoing — can still be acquired by birth/naturalization in BOTs
British Subject
Pre-1948 British subject status, not superseded by other nationality
No right of abode in UK
Yes — British passport
Essentially closed — historical holdover
British Protected Person (BPP)
Nationals of former British protectorates who didn't acquire citizenship at independence
No right to live/work in UK

United States Non-Citizen Nationals
US Non-Citizen National
Born in American Samoa or Swains Island. The distinction from other US territories (Puerto Rico, Guam, USVI) is critical: those territories are 'unincorporated but organized' under the Organic Act, which extended citizenship. American Samoa was never organized under an Organic Act, and Congress has never extended citizenship to its residents.
Cannot vote in federal elections (including presidential elections). Cannot hold certain federal jobs that require US citizenship. Technically classified as a 'national' not a 'citizen' under the Immigration and Nationality Act. In practice, US Non-Citizen Nationals have most of the same rights as citizens within the US — they can live and work anywhere in the US, serve in the military, and apply for citizenship through naturalization after 3 months of residence in any US state.
Yes — US passport, identical in appearance to a citizen's passport. The internal data page reads 'United States of America' with no indication of non-citizen national status.
By birth in American Samoa — ongoing. Can naturalize to full citizenship after 3 months of residence in any US state.
Vatican City
Vatican Citizenship
Employed by the Holy See in a qualifying role: the Pope (1 person), Cardinals resident in Vatican City (~50), members of the Pontifical Swiss Guard (~135), and senior officials of the Roman Curia and Vatican administration. Citizenship is granted by the Cardinal Secretary of State and requires a formal decree.
Citizenship expires automatically when employment or function ends — there is no permanent Vatican citizenship. Retired Cardinals who no longer reside in Vatican City lose citizenship. Swiss Guards who complete their service lose citizenship. The Pope's citizenship ends on death or resignation. Family members of Vatican employees do not automatically receive citizenship.
Yes — Vatican passport (dark red, gold embossed papal keys). Diplomatic status recognized by all countries that maintain relations with the Holy See.
Duration of employment or function only — citizenship is inherently temporary
Sovereign Military Order of Malta (SMOM)
SMOM Passport
Senior Knights of the Order (Fra' Milites): requires Catholic faith, noble lineage or exceptional service, and typically 20–30+ years of active membership. The Order has three classes: Knights of Justice (celibate, take religious vows), Knights in Obedience, and Donats. Only the highest ranks receive diplomatic passports.
Not recognized by all countries — recognized by ~100 states as a sovereign entity. Not a UN member state (has permanent observer status). The passport is a diplomatic document, not a travel document in the conventional sense — it does not grant visa-free access to most countries.
Yes — SMOM diplomatic passport (dark green, gold embossed cross)
Decades of membership + senior rank required — the most exclusive travel document in the world
