The choice of a second passport or citizenship should be guided by practical benefits rather than prestige. Certain programs carry significant drawbacks—such as travel restrictions, mandatory military service, difficult renunciation, or exposure to aggressive tax regimes—that can outweigh any perceived upside.
Sanctioned or Reputation‑Risk Countries
Passports issued by nations subject to international sanctions or that have a poor global reputation often limit travel and create administrative hurdles.
- Russia – Permanent residency can lead to citizenship within a year, but the Russian passport is barred from many European states. Holders also face compulsory military service and heightened scrutiny when opening bank accounts.
- Iran, Syria, Cuba, Vanuatu – Similar issues: limited visa‑free access, potential for sanctions, and a reputation that can affect personal and business dealings abroad.
Bottom line: The limited mobility and added legal complications make these passports unattractive for most investors.
Citizenship with Mandatory Military Service
Programs that automatically subject citizens (including children) to conscription pose a long‑term risk.
- Turkey – Investment‑based citizenship allows children to inherit nationality, but they become liable for Turkish military service. A safer approach is to obtain citizenship for oneself first and defer extending it to minors until they are older.
- Israel – All citizens, including women, are required to serve. Ongoing regional conflict adds uncertainty for future obligations.
In contrast, countries with little or no standing army—such as Costa Rica, which has no military—offer a cleaner profile for families.
Difficulty Renouncing Citizenship
Some states make it legally or administratively hard to give up nationality, which can trap holders in unwanted obligations.
- Argentina – While renunciation is possible, the process can be cumbersome. However, the Argentine passport enjoys a solid reputation and the country’s tax enforcement is relatively weak, so the downside is modest.
- Morocco – Renunciation is notably difficult, and the passport’s global standing is limited, making it a less attractive option.
When evaluating such programs, weigh the practical impact of potential renunciation hurdles against the passport’s benefits.
Citizenship‑Based Taxation
Countries that tax citizens on worldwide income impose ongoing reporting and financial obligations, regardless of residence.
- United States – U.S. citizens must file annual tax returns and disclose global assets, subject to extensive IRS scrutiny. This applies even to wealthy expatriates and can lead to double taxation without proper treaty relief.
- Potential future risk – Canada – If Canada were to enforce strict citizenship‑based taxation, similar constraints would arise.
For high‑net‑worth individuals, passports from jurisdictions without citizenship‑based tax (e.g., many Caribbean or European investment programs) are generally preferable.
Dual Nationality with an Adversarial Country
Holding passports from nations that are in direct conflict can expose the holder to legal peril, including detention or loss of citizenship.
- Russia vs. Ukraine – Dual holders risk arrest if either government discovers the other nationality.
- Armenia vs. Azerbaijan, Serbia vs. Kosovo, etc. – Similar risks exist where historic or ongoing disputes make dual allegiance dangerous.
If a new citizenship would place you on the “enemy” side of an existing conflict, it is advisable to decline the offer.
