Citizenship by investment (CBI) and naturalization often raise concerns about mandatory military service. While several countries maintain conscription laws, most CBI programs include exemptions, and even where service is required, it can usually be avoided through a fee.
Countries with conscription or registration
| Country | Legal requirement | Practical enforcement for investors / naturalized citizens | Typical exemption method |
|---|---|---|---|
| Mexico | Mandatory military registration for all males; selected individuals may be called to serve. | Not enforced for naturalized citizens or those born abroad. | Payment to obtain exemption. |
| Turkey | Mandatory military service for citizens. | CBI applicants are exempt; children can pay a small fee for exemption. | |
| Greece | 9–12 months of service for male citizens, depending on branch. | Not actively enforced; investors and their families are usually exempt. | Payment to avoid service. |
| Brazil | Selective conscription for men 18‑45, 12‑month term. | Children born to investors can pay to avoid service; registration is often lax. | |
| Serbia | No current conscription, but past mandatory service and possible future reinstatement. | If reinstated, investors could likely pay to avoid service, similar to Mexico. | |
| Romania | Previously offered CBI; currently volunteer‑based forces. | No mandatory service for investors; future changes possible. |
General patterns
- Exemptions for investors: Most CBI schemes deliberately exclude participants from conscription to keep the programs attractive. The financial contribution that secures the passport typically includes a provision that the holder will not be called up.
- Fee‑based avoidance: In countries where conscription is still on the books, a relatively modest payment can secure an exemption or a deferment. This practice is common in Mexico, Greece, Brazil, and would likely apply in Serbia if service were reinstated.
- Volunteer forces: Many European nations (e.g., Romania) and several Latin American states operate volunteer militaries. Even if a legal framework for conscription exists, it is rarely applied to naturalized citizens or investors.
- Risk considerations: Situations can change rapidly, especially in regions with heightened security concerns. The Ukrainian example illustrates that a country’s geopolitical climate may affect the likelihood of being called to serve, even for new citizens.
Practical advice for prospective investors
- Check the specific legislation: Verify whether a country’s conscription law applies to naturalized citizens or only to native-born males.
- Confirm exemption clauses: Review the CBI program’s official documentation for explicit statements about military service exemptions.
- Assess geopolitical stability: Countries in active conflict zones (e.g., Ukraine before the war) may pose higher risks of forced service or restrictions on leaving the country.
- Budget for potential fees: Even when exemptions exist, a nominal fee may be required to formalize the exemption; factor this into the overall cost of the citizenship program.
- Consider long‑term residency plans: If you intend to naturalize after a period of residence (e.g., Greece after 10 years), understand that mandatory service could become relevant, though enforcement is typically lax.
Summary
While mandatory military service remains a legal requirement in several nations, investors and naturalized citizens are generally exempt or can secure an exemption through a fee. The practical impact of conscription on CBI applicants is therefore limited, but due diligence—especially regarding a country’s security environment and the exact terms of the citizenship program—is essential before committing to a second passport.
