I also sued, but lost the Portuguese lotto on that one too (see here).
Where you were super-lucky was in getting a Bios appointment in 2025 (new process) instead of '24 (old process). I moved heaven and earth to make a 17-Dec '24 Bios appointment - wishing now I’d said “Sorry I can’t make it, can I do Bios in 2025 instead?”
I knew the PT GV would be bureaucratic. But I never thought it would be so chaotic, senseless and based on pure luck. To quote someone who messaged me privately about this, it’s “a disgrace, and speaks very poorly of the integrity and trustworthiness of the Portuguese State.”
