Start with the article supporting your application. “Knowledge is required” and “a specific examination is required” are different questions. The checked sources do not establish a single procedure for every situation.
Article 6(1) governs general naturalisation. The law also refers grandchildren of Portuguese citizens (Article 1(3)) and certain naturalisation routes to knowledge requirements. One rule cannot be applied to every route.

Keep evidence of submission and check how the procedure was registered. The transitional regime applies to the actual procedure; the date you started collecting documents is not enough.
Administrative procedures pending on 19 May 2026 remain governed by the previous wording of the Nationality Law.
