Acquiring Another Citizenship Still Costs You This One, Unless You Had Lived There Five Years

Section 9(1)(b) of Act No. 40/1993 Z. z. lists the acquisition of a foreign citizenship by an express act of will as one of the two ways Slovak citizenship is lost, and section 9(16) makes it automatic: a Slovak citizen loses citizenship on the day they voluntarily acquire a foreign one on the basis of an express act of will, which the provision defines as an application, a declaration or any other act directed at acquiring it. Two savings exist. Section 9(17) preserves citizenship where the foreign citizenship was a spouse's acquired during the marriage, or was acquired by birth or adoption, or was acquired by a minor child. Section 9(18), in force since 1 April 2022, preserves it where the citizen had permitted, registered or otherwise recorded residence in that state for at least five years and actually stayed there during that time. Both savings carry a duty: the acquisition must be notified in writing to the district office in the regional seat within 90 days, with documents. For the people caught between 17 July 2010 and 31 March 2022, section 7(7) is a restoration route - citizenship shall be granted, without the eight-year residence condition, to an applicant who lost it in that window and who had five years of residence in the state whose citizenship they took. Nothing of this kind appears on the Czech record for the same topic, which reads the naturalisation conditions in sections 13 and 14 of Act No. 186/2013 Sb. and says expressly that the absence of a renunciation requirement is read off those conditions rather than off any provision permitting dual citizenship. Whether Czech law makes acquiring a foreign citizenship a ground of loss was not read here.

Topics it changes

What it requires

  • Five years of recorded residence in the other state, and actual presence there, if you want to keep the Slovak citizenship
  • Written notice to the district office in the regional seat within 90 days of acquiring the other citizenship
  • Documents in paper form proving the acquisition and the length of residence

At a glance

Acquiring another citizenship
Ends Slovak citizenship on the day it is acquired

Section 9(16) of Act No. 40/1993 Z. z., where the acquisition is by an express act of will.

Saved if
You had at least 5 years of recorded residence in that state

Section 9(18) of Act No. 40/1993 Z. z., with actual presence there during that time.

Also saved if
The citizenship came from a spouse during the marriage, from birth, from adoption, or was acquired by a minor child

Section 9(17) of Act No. 40/1993 Z. z.

Notice
90 days, in writing, to the district office in the regional seat

Sections 9(17) and 9(18) of Act No. 40/1993 Z. z., each with its own list of documents.

Lost between 17 July 2010 and 31 March 2022
Citizenship shall be granted back, with no residence condition

Section 7(7) of Act No. 40/1993 Z. z., for an applicant who had five years of residence in the state whose citizenship they acquired.

Czechia
Not read: the Czech record covers the conditions for naturalisation, not the loss of citizenship

Its account of Act No. 186/2013 Sb. says the absence of a renunciation requirement is read off sections 13 and 14 rather than off any provision permitting dual citizenship.

Citizenship of the Slovak Republic may be lost a) by release from the state bond of the Slovak Republic on one's own application, b) by acquiring a foreign citizenship on the basis of an express act of will.

Two ways, and the second needs no decision by anybody.

Practical notes

Losing citizenship this way has consequences beyond the passport. Section 9(21) and (22) end a state service relationship or an office whose exercise is conditional on Slovak citizenship on the day of the loss.

The savings in sections 9(17) and 9(18) are not automatic in practice: each carries a 90-day notification duty with documents, and section 9(18) lets the district office record the loss where the five-year residence turns out not to be made out.

Nothing here was read about how the district offices apply the actual-presence test in section 9(18), which is where the saving will be won or lost.
