Citizenship by Naturalisation

Open Last verified July 2026

This is governed by the Mauritius Citizenship Act 1968. The USD 500,000 investment route to a reduced 2-year residence qualification rests on ministerial discretion. It is not an entitlement, and it is not published as a programme.

The Mauritian passport is the second-strongest in Africa, reaching 147 destinations including Schengen, the UK and China. That is genuinely useful. But naturalised citizens must renounce their existing citizenship, which makes this a replacement passport, not an additional one. That rules it out for most UHNW families.

What can go wrong
  • A naturalising alien must renounce their existing nationality and take the oath of allegiance, unless granted special approval. Citizens by origin in Mauritius have been allowed dual nationality since 1995. Naturalised citizens generally have not. This is the single most misrepresented fact about Mauritius in the citizenship industry.
  • The 2-year investor discretion is exactly that, discretionary. It is unpublished, unappealable, and not something to build a plan on.
  • The applicant must intend to continue residing in Mauritius. A plan to naturalise and then leave runs against the statutory condition.
  • Commonwealth citizens qualify after 5 years' residence. Everyone else needs 7. Check your nationality before you model the timeline.
  • There is no published processing standard, and decisions are made at the ministerial level. Timelines of two to three years are common, and there is no right of appeal.
