I have recently received an email from our law firm suggesting that we can go ahead with an early citizenship application submission, even though our 5-year date is mid-September. Here is their legal argument:
In practical terms, to clarify: the Constitutional Court states that the fact that an applicant began a residence process in 2020, 2021, 2022, 2023, and up to the date on which the new version of the Nationality Law is amended and published means, under Article 7(4) of the draft law, that he is allowed to submit the nationality process under Article 6 as it is currently in force. In other words, the applicant may rely on the requirement of five years of legal residency (along, obviously, with the personal documents and proof of sufficient knowledge of the Portuguese language), since the applicant had already begun the constitutive fact for the nationality process - namely, obtaining the residence permit (Golden Visa) — before the new Nationality Law entered into force and the decisive moment is not the submission date, but the decision date.
Apologies if this is posted on the wrong thread. I am typically late to the party.
