Acquisition of nationality through naturalization distinction in the treatment of these two categories with the exception that migrants are only eligible if they do not hold a passport or an identification document of any other country.103 Descendants of those eligible to register under the legal category of either stateless person or migrant are also eligible for registration if they were born in Kenya, are aged 18 years and above, have continuously resided in Kenya, and do not hold identification documents from any other country. To benefit as descendants, they must first demonstrate that there is sufficient proof that their parents fall within the legal categories either of a stateless person or migrant.104 For each of these three categories, they must also meet the following specific conditions set out in the 2011 Act: they must have adequate knowledge of Kiswahili or a local dialect; they must not have been convicted of an offence or sentenced to imprisonment for a term of three years or longer; upon registration they must intend to continue to permanently reside in Kenya or to maintain a close and continuing association with Kenya; and they must understand the rights and duties of a citizen. When the Act was enacted in 2011, it provided for a five-year window for persons falling within the above categories to apply for citizenship by registration, with the possibility for the Cabinet Secretary to extend this period for a further three years. Since then, the deadline has been extended again in 2016, 2017 and 2019 so that applications for Kenyan citizenship can be submitted until August 2021. Advocacy for further extension of the measure is ongoing. 103 Ibid. 104 Kenya Citizenship and Immigration Act of 2011, Section 17.
