Sources and methodology

Last reviewed 29 October 2026

Where the facts come from

I use primary sources first. The main ones:

Law No. 6/2010 of 21 June 2010, published in the Boletim Oficial No. 25, which amends and republishes the Nationality Law No. 2/92, and the original 1992 text on the website of the National People's Assembly.
EU Regulation 2018/1806 and the US Department of State list of countries subject to visa bonds.
News reports on the political situation: BBC and DW.
Practice notes and data published by BRIDGES: the Guinea-Bissau programme page, the country page, the Passport Index and the entry requirements page.

Each article shows an "Updated" date. It changes only when the facts are reviewed.
I give amounts in US dollars, as BRIDGES does.
I separate what the law says from what BRIDGES announces, and where sources differ, I show both.

the existence of a citizenship by investment programme in a law, decree or regulation of Guinea-Bissau;
the $90,000 contribution, the $5,000 stage 1 and the all-in estimate from $95,000, which come only from BRIDGES;
the rates for a spouse and children and the age limits for children;
the timelines beyond stage 1 (the BRIDGES page shows 1 to 2 weeks in its header but says final timelines are confirmed on the filing date);
whether any trip to Guinea-Bissau is required;
the number of destinations without a visa: 50 of 199 in the BRIDGES Passport Index against 44 of 202 on the BRIDGES programme page, and the entry regime for Ghana (visa-free on the programme page, electronic authorisation in the index);
the effect of the political transition and the postponed elections on naturalisation decrees.

All articles are reviewed at least once a quarter, and immediately after a change in the Nationality Law or in the published conditions.
