A single passport concentrates a range of legal, financial and security risks in one sovereign. In 2026 the passport‑ranking scores hide seven failure modes that can affect anyone who holds only one citizenship: revocation, exit bans, citizenship‑based taxation, conscription, limited consular protection, sudden downgrade of visa‑free access, and exposure to sanctions.
1. Citizenship can be revoked
- Kuwait – Since 2024 the state has stripped more than 70,000 people of nationality, a figure that rises to roughly 250,000 including dependents, many of whom become stateless.
- United States – A June 2025 Department of Justice memo made denaturalization a top civil‑enforcement priority. Civil denaturalization requires a lower burden of proof than criminal cases, offers no right to a court‑appointed lawyer, and can be filed at any time. Filings rose from under ten per year to over 30 in May–June 2026.
A single‑passport holder who loses citizenship has no fallback; dual nationals simply revert to their other nationality.
2. Governments control the right to leave
- In May 2026 the U.S. State Department began revoking passports of parents owing child‑support, starting with ≈2,700 people who owe $100,000 or more. The legal threshold is $2,500, meaning potentially hundreds of thousands could be affected.
- Revoked passports cannot be reactivated abroad; the holder may receive only a limited‑validity travel document back to the issuing country.
Exit bans are also used in tax disputes and civil cases, effectively trapping citizens inside a country’s borders.
3. Taxation tied to citizenship
- The United States taxes worldwide income of its citizens regardless of residence—a rule dating from the Civil War.
- Eritrea imposes a diaspora tax on its nationals.
- France narrowly missed a 2025‑2026 budget measure that would have extended tax liability for high‑earning expatriates for up to ten years after they moved abroad (threshold ≈ €235,500). The vote was 131‑132.
- Sweden, Finland and Germany already tax departing residents for a period after they leave.
Renouncing the only citizenship that imposes such taxes is impossible; a second passport is required to exit the tax regime.
4. Conscription obligations
- Croatia introduced compulsory military service in 2026, becoming the tenth EU state with a draft.
- Denmark extended conscription to women in 2025; Germany is rebuilding its draft; Ukraine lowered its mobilization age during the war.
A second passport does not erase conscription duties for the original nationality, but it can give children a separate nationality and a place to reside outside the reach of any single draft.
5. Limited consular protection
- Consular reach varies widely. Ireland, with a population of five million, operates over 100 diplomatic missions, while many countries have far fewer.
- During the 2025‑2026 Middle‑East air‑space closures, the UAE evacuated 500 golden‑visa holders, whereas citizens of states with limited diplomatic networks faced prolonged stranding.
Having a second citizenship expands the pool of governments that may provide evacuation or assistance.
6. Visa‑free access can be downgraded overnight
- The United Kingdom recently removed visa‑free entry for Saint Lucia and Nauru; the latter’s citizenship‑by‑investment program was cited as a factor.
- Ireland subsequently cut visa‑free access for Saint Kitts and Nevis, Saint Lucia and Nicaragua.
Visa‑free status is a privilege granted by the destination country and can be withdrawn without notice, regardless of the passport holder’s actions.
7. Nationality can become a liability under sanctions
- Citizens of a sanctioned state may face banking restrictions, heightened transaction scrutiny, frozen assets and capital controls, even if they reside elsewhere.
A second citizenship in a neutral jurisdiction can hedge against such exposure.
What a second passport actually solves
- Exit protection – A second passport restores the ability to leave if the primary passport is revoked or an exit ban is imposed.
- Consular redundancy – It adds another state with an unconditional duty to admit and protect the holder.
- Tax‑avoidance pathway – Only a second citizenship allows renunciation of a tax‑based nationality without becoming stateless.
- Mobility resilience – It safeguards against sudden loss of visa‑free access and algorithmic “invisible walls” that filter travelers by risk profiles.
What it does not eliminate:
- The original citizenship’s conscription duties (unless the individual renounces that citizenship).
- Existing tax obligations that arise before renunciation.
- The risk of being caught in sanctions if the primary nationality remains under restriction.
Practical considerations
- Timing – Acquire a second citizenship or a robust residence permit before a crisis hits; programs can become more restrictive or expensive with little notice.
- Dual‑nationality requirements – Ensure the second country permits dual citizenship and that the primary country does not prohibit it.
- Due diligence – Review investment thresholds, background‑check procedures and the scope of rights (e.g., consular assistance, tax obligations).
- Exit strategy – Keep the second passport valid and up‑to‑date; a lapsed passport can undermine the very protection it is meant to provide.
In summary, while a strong first passport may suffice for routine travel, the concentration of revocation, exit, tax, conscription, consular, visa‑access and sanctions risks in a single sovereign makes a second citizenship a strategic hedge for those who can afford it.
