The exact figure of 583,000 resolved pending regularisation processes does not appear in any source found; the closest official figure is 'more than 525,000 processes decided, of which about 473,000 favourable' plus 763,000 attendances, as reported by the government in May 2026.
Only a single primary (government) source could be retrieved, and it is a lower-bound figure ('mais de 525 mil') from an earlier date (May 2026) than the session (October 2026); the resolution count could plausibly have grown between the two dates, so the claim is not contradicted.
The claim also asserts that the reforms 'halved human trafficking', a separate factual assertion not addressed here.
The figure is a government/AIMA statistic rather than an independently audited number; the government itself acknowledges methodological differences between AIMA and INE migration data.
