Kazakhstan citizenship — turnkey (dual citizenship is prohibited)

Confirmed by going directly to egov.kz: under Article 10 of the Constitution of Kazakhstan and the Law 'On citizenship of the Republic of Kazakhstan', a citizen of Kazakhstan is not recognised as a citizen of another state at the same time. On acquiring Kazakhstani citizenship you must renounce your previous one; if a citizen of Kazakhstan later acquires foreign citizenship without renouncing the Kazakhstani one, by law they must give notice of this within 30 calendar days and hand in their passport or ID card, otherwise the internal affairs authorities register the loss of Kazakhstani citizenship themselves during a check, and continuing to use Kazakhstani documents after the loss of citizenship carries a fine (different official sources give 100 to 200 MCI depending on the specific offence under Article 496 of the Code of Administrative Offences of Kazakhstan).

A note on the date: July 2025 was announced initially, but that was only the date the draft order was published for public discussion (14.07.2025, Kursiv Media). The order itself, signed by the acting Minister of Science and Higher Education, came later and took effect on 26.08.2025 (confirmed by Caliber.Az and Zakon.kz). The changes are not unambiguously a 'relaxation': the minimum mark for the Kazakh language was lowered from 36 to 15, BUT the minimum mark on the fundamentals of the Constitution of Kazakhstan was raised from 9 to 20, the requirement on the history of Kazakhstan stayed at 15 points, and the overall pass threshold across all subjects was cut by about 10%. So the language has become easier to pass, and the Constitution harder.
