Nationality rules differ enormously between countries, and this is not a page that can tell you whether you qualify. Some countries pass citizenship down indefinitely; others stop at one generation born abroad, require registration before a deadline, or do not permit dual nationality at all. What follows is how to find out for Slovakia, and what to settle before you spend anything.
Quick facts
Slovakia has three consular offices in the United States, in Denver, New York and Washington, D.C. With more than one, the office that matters is the one whose district covers your state of residence — and that is not always the nearest.
Slovak consular offices in the United States
Applications and enquiries go through the office whose district covers your state, though the decision itself is taken in Slovakia:
The questions that decide your case
- How far down does descent run? Through a parent is common; through a grandparent is much rarer; through a great-grandparent is unusual anywhere.
- Is there a deadline? Several countries require a child born abroad to be registered within a set period, after which the claim is lost.
- Does Slovakia permit dual nationality? Only if you have lived in the other country long enough. A Slovak loses citizenship on the day of acquiring a foreign one — unless, at that moment, they had at least five years of recorded residence in that State. The residence has to exist already; it cannot be built up afterwards.
- Does the line pass through either parent? Some nationality laws were paternal for decades and were reformed later, sometimes with retroactive effect.
- What obligations come with it? Military service and tax residence attach to nationality in some countries regardless of where you live.
Documents a claim by descent normally rests on
- Birth certificates establishing the unbroken line, each certified for use abroad.
- Marriage certificates covering every change of surname in that line.
- The ancestor’s Slovak passport, identity card or other proof of nationality.
- Evidence of whether and when an ancestor naturalised elsewhere, which in some countries breaks the line.
- Translations into Slovak where required.
Before spending money on this
Ask the consular office what Slovak law actually allows in your circumstances before engaging anyone to help with it. Genealogists and specialist firms exist and can be useful where records are old or scattered, but they are not a substitute for knowing whether the claim exists at all — and that answer is free.
If your own immigration position in the United States is unresolved, take advice from an immigration lawyer before approaching any foreign authority.
Slovakia: the five-year residence test decides it
Under § 9 of Act No. 40/1993 on citizenship, a Slovak citizen loses Slovak citizenship on the day they voluntarily acquire a foreign citizenship. There is no proceeding and no decision: the authority merely records what has already happened.
The exception, added in 2022, is a residence test. Loss does not occur if the citizen had, at the time of acquiring the foreign citizenship, at least five years of permitted, registered or otherwise recorded residence in that State — and the condition counts as met only if the person was actually present there during that time. So:
- Naturalised after the usual five years as a U.S. permanent resident, actually spent in the U.S. — Slovak citizenship is kept.
- Naturalised through the three-year marriage route, or after years mostly spent elsewhere — Slovak citizenship is lost on the day of the oath.
Nothing is applied for beforehand. This is the part most often got wrong: there is no permission and no retention permit. The exception works by law if the facts are there. What there is, is an obligation afterwards: written notification within 90 days to the district office at the regional seat, with paper documents proving both the acquisition and the length of residence. If the office finds the condition unmet, it notifies the loss and records it.
For those caught by the harsher rule, the way back is a right, not a favour. Between 17 July 2010 and 31 March 2022 the law stripped citizenship with no exception at all. § 7(7) now says Slovak citizenship shall be granted to anyone who lost it in that window and meets the same five-year residence test, waiving the normal requirement of residence in Slovakia. It is granted by the Ministry of Interior, and the application can be filed in person at a Slovak consulate in the United States.
