This is a very informative summary and thank you @goncalomendesleal for writing it.
We applied for our GVs in November 2021, received our residency cards in April 2024 (with a little help from a kindly judge), moved here and signed the deed on our Lisbon property in July 2024, became tax resident with NHR in September 2024, my partner began employment in Lisbon in October 2024, I got my A2 certificate from PLA in March 2025, and we have just submitted our first tax returns online for the four required months of 2024.
[As an aside, we applied for GVs in 2021 when we were living in Asia and our future plans were uncertain so it seemed like a good hedge to give us options but in the event we decided we would move here permanently anyway.]
We will need to renew the residency cards in April 2026 and fully intend to apply for citizenship in November 2026.
Is there anything else we could or should be doing now to further de-risk this?
