Denmark’s parliament is considering a 10-year probation rule that would let the state strip newly naturalised citizens of their passports if they later commit crimes that would have blocked citizenship in the first place.
The proposal is buried in parliamentary resolution B 46, which instructs the government to restore a former section of the citizenship law and add several new conditions by the end of 2026. The 10-year window is the most concrete detail in the bill text, yet it has received less attention than the symbolic parts of the same proposal. That is a mistake, because for anyone on the path to Danish citizenship, the practical consequence matters more than the political signal.
A second class citizenship for a decade
The resolution calls for reinstating former paragraph 3A of the citizenship law. That would create a probation period starting from the day of naturalisation. During those 10 years, newly minted Danes could lose their nationality if they commit offences that would have disqualified them during the application process. Parliament has not yet specified exactly which crimes would trigger revocation, but the language suggests anything serious enough to block an initial application.
This is not about keeping bad actors out. It is about monitoring them for a decade after they are already in. For long-term residents who meet every requirement at application, the rule means permanent citizenship is not actually permanent until 2036 if the law passes this year.
Citizenship by parliament, not by desk
Denmark grants citizenship through legislation, not through ordinary administrative decisions. Folketinget passes citizenship laws twice a year, listing approved applicants by name. The latest such law, L 217, was adopted on 11 June 2025. That makes the system unusually formal compared with most EU states, where naturalisation is a ministerial act or court ruling. The formal process also means changes take time. B 46 is a resolution telling the government to draft a bill, not a bill itself.
The timeline matters. The resolution sets a deadline of late 2026 for the government to bring legislation forward. Even if ministers comply, any actual rule change would still need a majority in parliament and would follow the standard citizenship cycle. That gives people currently applying some breathing room, but not much comfort.
Israel and scrutiny added to the package
The same resolution demands that applicants sign a statement recognising Israel‘s right to exist. It also calls for a broad review of citizenship administration and tougher screening of applicants’ values. The combination turns the proposal into something broader than security policy. It mixes foreign policy symbolism with domestic integration enforcement.
For internationals, the Israel clause is politically awkward but administratively simple. You sign or you do not apply. The probation period is harder to navigate because it creates risk after you think the process is finished. That uncertainty is the point. The proposal assumes some people who look compliant today will prove otherwise tomorrow, and the state wants the power to act retrospectively.
What this means for applicants now
People already on the citizenship track should treat B 46 as a political process, not an immediate legal change. Folketinget’s own guidance says applicants do nothing during the parliamentary phase except wait for a letter from the Ministry if their name appears in a law. Once citizenship is granted, you must attend a municipal ceremony and sign the constitutional declaration. Without that ceremony, citizenship is not completed.
The supplied sources do not indicate whether the 10-year probation would apply retroactively to people already naturalised. That is a major gap in the public record. If the rule applies only to future applicants, current citizens are safe. If it applies backwards, thousands of naturalised Danes suddenly face a decade of conditional status they did not agree to.
Why this is different
Most debates about citizenship focus on who gets in. This proposal focuses on who stays in after the door closes. That shift is significant because it treats naturalisation not as a completed legal act but as the start of a long probationary relationship. The model assumes integration is reversible and that the state should keep checking long after the oath is signed.
For expats who have spent years building a life here, the proposal is a reminder that formal equality takes longer than the law suggests. Denmark already demands language tests, employment history, clean records and years of legal residence before citizenship. Adding a 10-year probation period on top means new citizens will not have the same security as those born Danish until well into middle age for many applicants.
The government has until the end of 2026 to draft the follow-up bill. Until then, applicants wait and wonder whether the rules will change before their names reach parliament.
