Conscription is spreading across Europe again, and a second passport is sold as the way out. Sometimes it is. But the wrong passport can hand your sons a military obligation they never had. Here's the country-by-country reality.
For two decades, conscription looked like a relic in most of the West. That's over. Since 2022 it has been coming back fast, and a second passport is increasingly pitched as the clean escape, a way to give yourself or your sons a door out of the draft.
It can be. But the advice usually skips the dangerous half of the truth: a second passport doesn't only fail to help in some cases, it can actively create a military obligation that didn't exist before. Pick the wrong country and you've signed your teenage son up for service in a place he's never lived. Whether a passport is an exit or a trap comes down to details most people never check until it's too late.
Conscription is expanding, not fading
The backdrop matters, because the pressure is building. Around 60 countries still conscript at least some of their citizens, and the list is growing. Latvia reinstated conscription in 2024. Croatia brings it back in 2026. Germany passed a hybrid voluntary-and-mandatory service law in December 2025, with the first mandatory questionnaires going out in January 2026. Sweden and Denmark are expanding their gender-neutral models, and France, Belgium and Poland all announced new national-service tracks in 2025. Inside the EU, mandatory service now exists in Austria, Cyprus, Denmark, Estonia, Finland, Greece, Latvia, Lithuania, Sweden, and now Croatia.
So this isn't a fringe concern for a handful of countries. It's a widening one, and it interacts with citizenship in ways that cut both directions.
The three questions that decide everything
Whether a second passport helps or hurts depends on three things, in this order.
First, how your current country treats its citizens who hold another passport. Some bind you regardless. Second, what the new passport's country demands of its own citizens, because acquiring it can add an obligation. Third, timing: the age at which citizenship is acquired, especially for a son, can decide whether service is owed at all.
Get those three right and a passport is a genuine exit. Get them wrong and it's the opposite.
Where it helps, where it traps
| Country (passport) | Who is liable | Help or trap? | The catch |
|---|
| South Korea | Men, 18–21 months, including dual nationals | Traps | Male dual nationals must renounce by 31 March of the year they turn 18, or they can't renounce until they finish service or age out in their late 30s |
| Israel | Men ~32 months, women ~24; new immigrants under the Law of Return | Can add liability | Immigrants are liable, with reductions based on age at arrival |
| Singapore | Male citizens and permanent residents, 22–24 months | Can add liability | Renouncing to avoid National Service bars future return; a known trap for boys who hold PR from childhood |
| Greece | Men, 9–12 months; dual nationals included | Can add liability | Liable unless you've served elsewhere or qualify for exemption; diaspora Greeks get caught if they reside or spend real time there |
| Cyprus | Men, ~14 months | Can add liability | Applies to male citizens including those of Cypriot descent; relevant given how many take Cypriot citizenship |
| Turkey | Men, 6–12 months | A soft obligation | Paid exemption ("bedel") available; citizenship-by-investment holders are effectively never called up |
| Switzerland | Men; serve or pay a tax | Adds a cost if resident | Non-servers pay a military-exemption tax of about 3% of income until their mid-30s; resident dual nationals are liable |
| Russia / Ukraine / Belarus | Men; binds nationals regardless of a second passport | Doesn't help | A second passport doesn't release you; evasion is a criminal matter on return, and Ukraine bars most men from leaving under martial law |
| Germany | All German men 18+ under the December 2025 law | Doesn't help | The obligation attaches to every German man equally, dual national or not |
| Finland | Men only, ~6–12 months (women volunteer) | Can add liability | Long-standing and broad for men; dual-national men resident in Finland are liable |
| Sweden | Men and women (gender-neutral since 2017), ~9–15 months | Can add liability | Selective: only part of each cohort is called after assessment, so the obligation exists but call-up isn't universal |
| Norway | Men and women (gender-neutral since 2015), ~12 months | Can add liability | Highly selective: most are never called, but the legal obligation applies to citizens |
| Estonia | Men only, 8 or 11 months | Can add liability | Broad male conscription; dual-national men resident there are liable |
| Latvia | Men 18–27, 11 months (reinstated 2024) | Can add liability | Recently reinstated; women voluntary for now; draft evasion is prosecutable |
| Lithuania | Men ~18–26, ~9 months (reinstated 2015) | Can add liability | Conscripts selected by lottery from the cohort; women volunteer |
| United States | Men 18–25 must register for Selective Service | Doesn't remove it | No active draft, but registration is mandatory and tied to benefits; a second passport doesn't exempt a US-resident man |
| Caribbean CBI, Ireland, UK, Canada, Australia, New Zealand, Argentina, Portugal, Italy, Spain | No active conscription | Clean | These add no military obligation, the genuine "exit" passports |
The traps worth understanding
A handful of these deserve spelling out, because they're where people get hurt.
South Korea is the strictest in the world. A boy born to Korean parents abroad, a Korean-American say, is a dual national, and under the Nationality Act he must renounce his Korean citizenship by 31 March of the year he turns 18. Miss that window and he's locked in: he cannot renounce until he has either completed military service or aged out of eligibility in his late thirties. Families who don't know the rule discover it when a teenage son is suddenly unable to give up a citizenship he never used.
Greece catches diaspora families a softer but real way. Greek citizenship, including citizenship acquired by descent, carries a service obligation for men. So claiming a Greek passport through a grandparent, an attractive route to an EU passport, can hand your son a conscription liability as part of the package. Cyprus works much the same way, which matters because Cypriot descent and naturalisation are popular EU routes. It's a clean example of why citizenship by descent needs checking for military strings before you pursue it, not after.
Singapore is unforgiving for boys raised as permanent residents: National Service liability attaches young, and trying to escape it by renouncing or staying away closes the door on ever living there again. The post-Soviet states, Russia, Ukraine and Belarus, simply don't accept that your second passport matters. To them you remain their citizen with their obligations, and evasion becomes a criminal problem the moment you set foot back.
The Selective Service trap Americans forget
Americans tend to assume conscription is somebody else's problem. It isn't, quite. The United States has no active draft, but every man living in the US between 18 and 25, including most male immigrants and many male dual nationals resident there, is legally required to register with the Selective Service System. The draft itself is dormant, but the registration is real and is tied to things like federal student aid, government jobs and, for immigrants, future naturalisation. A second passport does nothing to remove it. It's a paperwork obligation rather than a year in barracks, but it's the one most US readers don't know applies to them.
How people actually get out
Naming the traps is only half the job. The exits are specific, and they matter.
Completing service elsewhere is the cleanest. Many conscription countries treat military service already done in another country as discharging the obligation, so a dual national who served where he lived may owe nothing to the second state. Ageing out is the next route: most systems end liability at a set age, often the mid-to-late 30s, after which the passport carries no risk at all, which is why acquiring some of these citizenships later in life is far safer than at 17. A paid exemption is the third, and Turkey is the clearest example, where eligible men can pay the "bedel" fee and complete a token training period instead of full service. And in several countries the age at which a man naturalises decides everything: naturalise after the relevant cut-off and the obligation may be shorter or gone.
Renunciation is the route people reach for first and it's the most misunderstood. It works only where your home country lets you renounce freely and the timing is right. In South Korea and Singapore, the rules are deliberately built so you cannot renounce your way out of service once the clock has started, which is exactly why those two are the dangerous ones.
A family example
Consider a couple in California with a teenage son, both parents Korean-born, the boy a Korean-American dual national who has never lived in Korea. To them his second passport looks like a harmless inheritance. Under Korean law it's a clock. If they do nothing, his right to renounce expires on 31 March of the year he turns 18, and from that point he cannot give up Korean citizenship until he has served or reached his late thirties, with travel to Korea carrying real risk in the meantime. The fix is simply to renounce before the deadline, but only a family that knows the rule exists will act in time. That single date is the most consequential line in this entire article for anyone it applies to.
Where a second passport genuinely helps
The flip side is the useful part. If escaping a draft is the actual goal, the clean options are the countries with no conscription at all: most of the Caribbean citizenship-by-investment nations, Ireland, the UK, Canada, Australia, New Zealand, and much of Latin America, where countries like Argentina abolished compulsory service decades ago. A passport from one of these adds mobility and optionality without adding a military obligation, which is the whole point of acquiring one as insurance.
The practical takeaway is simple. A second passport is a powerful tool against conscription, but only if you treat the military question as a feature to check before you choose the country, exactly the kind of detail that separates a real plan from a brochure. If you're still deciding between a passport and a residence permit in the first place, that choice comes before this one.
Common questions
Can a second passport get me out of the draft? Sometimes. If your home country doesn't bind its dual nationals, a passport from a no-conscription country gives you a genuine exit. But if your origin country binds you regardless (like Russia or Ukraine), or the new passport carries its own obligation (like Greece or Singapore), it won't help, and can hurt.
Which second passports have no military service at all? The Caribbean investment-citizenship countries, Ireland, the UK, Canada, Australia, New Zealand, and most of Latin America including Argentina. These add no conscription liability.
Can getting a passport create a military obligation I didn't have? Yes, this is the overlooked risk. Greek, Cypriot, Israeli, Singaporean and Korean citizenship can all attach a service obligation, including for sons who acquire it by descent or from childhood residency.
Do Americans have to worry about this? There's no active US draft, but men aged 18 to 25 living in the US, including many immigrants and dual nationals, must register with Selective Service. A second passport doesn't remove that obligation.
My son is a dual citizen. What should I check? The single most urgent case is South Korea, with its hard deadline of 31 March of the year a male dual national turns 18. More broadly, check the origin country's rules for dual-national sons and the age cut-offs, well before he turns 18.
Does claiming citizenship by descent carry conscription risk? It can. A passport through a grandparent in a country with conscription (Greece and Cyprus are the common ones) can carry the obligation with it. Check before you apply.
This is general information, not legal advice. Conscription rules are politically sensitive, vary by your exact circumstances, and change with governments. Several countries on this list have changed their rules in the past two years. Verify with the relevant defence ministry or consulate, and take professional advice, before relying on any of it.
