Eligibility for nationality receives the third lowest score found in the 28 MIPEX countries. Only long-term residents are eligible after five years of residence, which for most migrants means waiting at least ten years in total. The second- and third-generation (Czech-born children and grandchildren of migrants) must also naturalise to become citizens of their country of birth. Officially, Czech nationality is available for all those who have not committed a crime in the last five years and who pass the simple, oral language interview. In practice, the state rejects applicants if it considers that their income, level of integration or civic conduct is not good enough. Although the state can reject an applicant on many grounds, migrants enjoy a favourable security of status since, once naturalised, their citizenship can never be withdrawn. Some naturalising migrants can become dual nationals through bureaucratic exceptions.
