Rwanda.

A foreigner may apply for Rwandan nationality by acquisition on grounds of 'substantial sustainable investment or activities' in Rwanda, supported by a letter from a relevant public body describing the investment, plus integrity and no threat to national security (Organic Law 002/2021.OL of 16 Jul 2021, art. 15, in force on publication 28 Jul 2021). The 2022 ministerial order (art. 12) asks for proof of properties owned and of registration as an investor in Rwanda. No minimum amount, price or fee schedule is set in the texts read, so the route is discretionary; launched is the law's in-force date, as the first text found that names investment as a ground (the 2008 law it replaced was not read). Separate investor residence permits exist (permit class A1 'investor' under the immigration ministerial order, defined by reference to the investment law); they were not added because no amount was found in the immigration texts. No counts of nationality grants on this ground found. Status left empty: no document says whether anyone has been naturalised this way.
