Permanent residence in Slovakia can be obtained after 5 years of residence on the basis of residence permit. For example, an entrepreneur or a company owner has been in business for 5 years and lived with his family in Slovakia, then he and the whole family can receive permanent residence. This status is given for life; it is no longer necessary to renew it.
Having received the status of permanent residence, you have almost all the same rights as citizens of the Slovak Republic, with the exception of the right to vote in elections. And after another 5 years (cumulatively 10 years from the date of first obtaining a residence permit), you can become a citizen of Slovakia. For this you need to pass the exam on the knowledge of the Slovak language. As a rule, many people who receive the status of permanent residence do not seek to obtain citizenship, as they are already satisfied with everything.
