Portugal Expats: Update Address & NISS to Avoid Residency Delays

Thousands of migrants living in Portugal have just been asked to do a tiny chore that could decide whether their residence cards arrive on time, their citizenship files keep moving, or their applications get stuck in limbo. The government’s migration agency, AIMA, says a quick online update of home address and Social Security Number (NISS) will solve most of the bureaucratic bottlenecks that dominated last year’s complaints.

At a Glance

• Who is affected? Anyone whose AIMA file still carries an old address or no NISS at all.

• Why now? The agency wants to prevent a repeat of the 2025 backlog that left 387 000 processes piling up.

• How long will it take? AIMA promises a response within 2 business days after the form is submitted.

• Key risk if you ignore it: Missing renewal notices could trigger automatic refusal of residency or citizenship applications.

The urgency behind the email

Complaints exploded last year after tens of thousands of immigrants failed to receive their renewed residence permits simply because letters were sent to outdated addresses. AIMA now concedes that “bad data equals bad service” and is urging every foreign resident to correct the records before the next renewal wave in spring. The agency’s own numbers show that 37 % of grievances in early 2025 related to delayed documents, many tied to incorrect contact details. On top of that, the insistence on a valid NISS—which was not mandatory on older permits—became a fresh sticking point. By flagging the issue now, officials hope to avoid another spike in rejections like the 76 000 notifications returned to sender last February.

Step-by-step: updating address or NISS in minutes

Go to the AIMA contact form online.

Choose “Renewal Portal” as the main subject.

In the sub-subject menu pick “Update Address” or “Insert/Correct NISS”.

Upload proof of the new address or the official NISS certificate.

Submit and keep the confirmation e-mail; AIMA says the file will show as amended inside 48 hours.

The agency insists the same workflow applies whether you are fixing a typo, adding a brand-new NISS or changing apartments. Applicants can track progress by logging back into the portal—though user groups still complain that the system often freezes during peak hours.

AIMA under public scrutiny: statistics paint a troubling picture

Portugal’s Portal da Queixa recorded 1 847 grievances against AIMA by November 2025, up 6.5 % year-on-year. The steepest growth came in the third quarter, when complaints surged 45 % compared with 2024. Analysts say three patterns dominate: long waits for residence cards, confusing or no replies to e-mails, and technical glitches in the new renewal portal. Administrative issues—where wrong addresses and missing NISS codes sit—made up 41.5 % of all reported cases. Despite a high-profile “task force” that processed 93 % of interest declarations by December, the numbers reveal a system still straining under demand.

Legal voices and civil society weigh in

Immigration lawyers applaud the two-day target yet warn it is “only a patch” unless AIMA tackles deeper IT flaws. Several firms say they continue to file court injunctions to force interview dates. Meanwhile, SOS Racismo, Casa do Brasil and other NGOs from Lisbon to Porto accuse the agency of “systemic failures and rights violations”—from unanswered phone lines to portals that crash without generating protocols. They argue that real credibility will come only when the promised deadlines are consistently met and applicants can monitor each step transparently.

What to watch in 2026

The Interior Ministry wants the backlog cleared before summer tourism drives labour demand. Success will hinge on three markers:

• AIMA’s ability to keep the 2-day turnaround for data corrections.

• Seamless integration of the NISS database with Social Security to end the “NISS not recognised” error.

• A published quarterly dashboard that shows how many renewals were resolved, denied or still pending.

For the 800 000-plus foreign residents who now call Portugal home, logging in, updating one form and saving that confirmation e-mail may be the easiest way to ensure their status—and plans—remain on track this year.
