Why AIMA Is Issuing This Warning Now
According to The Portugal News, AIMA issued formal guidance in July 2026 urging foreign nationals to "pay close attention to how their names appear on official documents" because "inconsistencies were found to be causing delays and administrative complications in some cases." AIMA specifically warned that applicants using its online contact forms should ensure that "the spelling, order and formatting of their names are identical across all documents before submitting requests for information or clarification."
This warning comes as AIMA has digitized its application processes and implemented stricter identity verification protocols. When AIMA's online renewal portal and digital application systems cross-check your name across multiple databases — your visa record, your prior residence permit, your tax authority (Finanças) record, your Social Security record — any mismatch triggers an automatic flag for manual review. In 2025 and early 2026, thousands of applications were delayed or sent back to applicants with requests for corrected documents due to name inconsistencies.
AIMA is now proactively warning applicants to verify name consistency before submission to reduce delays and administrative burden on both applicants and AIMA staff. This is a preventable problem — but only if you check your documents carefully before you submit your application.
What Name Discrepancies Look Like and Why They Happen
Name discrepancies can take many forms. Here are the most common examples AIMA has flagged:
- Different surname order: Your passport shows "Maria Silva Santos" but your birth certificate shows "Maria Santos Silva". In many Portuguese-speaking and Spanish-speaking countries, people use both their father's and mother's surnames, and the order can vary depending on local convention.
- Missing middle names: Your passport includes all your given names ("João Pedro Silva Santos") but your visa application only included your first and last name ("João Santos"). Now AIMA's system shows two different name variations for the same person.
- Hyphenated vs non-hyphenated surnames: Your marriage certificate shows "Garcia-Lopez" but your passport shows "Garcia Lopez" without the hyphen. This is common when one country uses hyphens for compound surnames and another does not.
- Initials vs full names: Your bank statement or employment contract uses "M. Silva" but your passport shows "Maria Silva". Some institutions abbreviate middle names or given names, which can create discrepancies when AIMA cross-checks documents.
- Transliteration differences for names from non-Latin scripts: Your Russian passport was transliterated as "Sergey" but your Portuguese visa shows "Sergei". Different countries use different transliteration standards for Cyrillic, Arabic, Chinese, Japanese, and other non-Latin scripts.
- Post-marriage surname changes not reflected consistently: You changed your surname after marriage but some documents still show your maiden name. This is especially common if you obtained documents before and after marriage without updating older documents.
Any of these discrepancies can trigger AIMA to flag your application for identity verification, which can delay processing by weeks or months or result in a request for corrected documents. In some cases, significant name mismatches have led to application rejections because AIMA could not confirm that all the documents referred to the same person.
Who Is Most at Risk: Compound Surnames and Non-Western Naming Conventions
Applicants with compound surnames (common in Spanish-speaking and Portuguese-speaking countries, where people use both their father's and mother's surnames), hyphenated names (common after marriage in many countries), matronymic or patronymic naming conventions (common in Iceland, parts of the Middle East, and some African countries), or names that use non-Latin scripts (Russian, Arabic, Chinese, Japanese, Korean, etc.) are most at risk for name discrepancies.
These naming conventions can lead to inconsistencies when documents are issued by different countries or translated into Portuguese. For example:
- Brazilian applicant named "João Silva Santos": In Brazil, "Silva" is the mother's surname and "Santos" is the father's surname. The full surname is "Silva Santos". But when João applied for his Portuguese visa, the consulate recorded only "Santos" as his surname. Now João's visa shows "João Santos" but his passport shows "João Silva Santos". AIMA's system flags this as a discrepancy.
- Russian applicant named "Сергей Иванович Петров" (Sergey Ivanovich Petrov): Sergey's passport was transliterated as "Sergey Ivanovich Petrov" but the Portuguese consulate transliterated his name as "Serguei Ivanovitch Petrov" when issuing his visa. Now Sergey has two different name variations in AIMA's system.
- Spanish applicant named "María García López": In Spain, "García" is the father's surname and "López" is the mother's surname. María's full surname is "García López". But when she married in Portugal, the Portuguese marriage certificate recorded her name as "María López García" (reversing the order). Now María's passport shows "García López" but her marriage certificate shows "López García".
If your name falls into any of these categories, you are at higher risk for name discrepancies and should pay extra attention to verifying consistency across all your documents before submitting your AIMA application.
How to Check Your Documents for Name Consistency Before Submission
Gather all documents you plan to submit with your AIMA application. At a minimum, this includes:
- Passport (all pages showing your name)
- Portuguese residence visa (D7, D2, work visa, family reunification visa, etc.)
- Birth certificate (if required for your application type)
- Marriage certificate (if applicable)
- Employment contract or proof of self-employment
- Bank statements or proof of financial means
- Rental contract or proof of accommodation
- Portuguese tax registration (NIF certificate)
- Social Security registration (NISS certificate, if you already have one)
- Any other supporting documents (diplomas, professional licenses, etc.)
For each document, write down exactly how your full name appears — including the order of your given names and surnames, whether middle names are included or omitted, and whether surnames are hyphenated or separated. Compare all the name variations. If your name appears identically on every document, you are clear. If you find discrepancies — even minor ones like a missing middle name or a different surname order — you need to address them before submitting your application.
Pay special attention to these critical name matches:
- Passport vs Portuguese visa: This is the most important match. AIMA will cross-check your passport name against the name on your visa record. These must match exactly.
- Passport vs NIF registration: Your Portuguese tax number (NIF) is linked to your name in the tax authority's database. If your NIF was issued with a different name variation than your passport, this can cause problems.
- Passport vs NISS registration: If you already have a Social Security number (NISS) from a prior residence period, make sure the name on your NISS record matches your current passport.
What to Do If You Find a Name Discrepancy
If you find a name discrepancy, the solution depends on which document contains the mismatch:
If the discrepancy is on a document you control (employment contract, rental contract, bank statement, etc.)
Contact the issuing party (your employer, landlord, or bank) and request a corrected version with your name spelled exactly as it appears on your passport. Most institutions will issue a corrected document upon request, especially if you explain that it is needed for an official government application.
If the discrepancy is on a Portuguese visa
Contact the Portuguese consulate that issued your visa and explain the discrepancy. In some cases, the consulate can issue a correction or a letter confirming the error. However, visa corrections are often not possible after the visa has already been issued and used. In that case, the best approach is to include a cover letter with your AIMA application explaining the discrepancy and providing supporting evidence (such as a notarized affidavit or a letter from your home country's embassy) confirming that the different name variations all refer to the same person.
If the discrepancy is on your birth certificate or marriage certificate
You may need to obtain a certified translation or apostilled copy that matches your passport. If your birth certificate was issued in a language other than Portuguese, you must submit a certified translation. Make sure the translator uses the same name spelling and order as your passport. If your marriage certificate shows a different surname than your passport (for example, because you changed your surname after marriage but your passport was issued before the name change), you may need to submit both your maiden-name passport and your marriage certificate, along with a cover letter explaining the name change.
If the discrepancy is significant or you are unsure how to resolve it
Consult an immigration lawyer. Name discrepancies can be complex, especially for applicants with non-Western naming conventions or names from non-Latin scripts. A lawyer can advise you on the best approach and help you prepare supporting documentation to explain the discrepancy to AIMA.
What Happens If AIMA Flags Your Application for Name Verification
If AIMA flags your application for name verification, you will typically receive a request for additional documentation. This may include:
- A notarized affidavit confirming that the different name variations all refer to the same person
- A letter from your home country's embassy or consulate confirming your identity and explaining the name discrepancy
- Corrected versions of documents that contain the name mismatch
- Certified translations of birth certificates or marriage certificates that clarify the name issue
Responding to an AIMA request for additional documentation can delay your application by several weeks or months, depending on how quickly you can gather the required documents and how long AIMA takes to review them. In some cases, failure to provide satisfactory documentation can result in application rejection.
The best approach is to prevent this problem by verifying name consistency before you submit your application. If you know you have a name discrepancy, address it proactively by including a cover letter and supporting documentation with your initial application, rather than waiting for AIMA to flag it.
Frequently Asked Questions
What kinds of name discrepancies can cause problems with AIMA applications?
AIMA has flagged several common name discrepancies that can delay or complicate residence permit applications: (1) Different surname order — for example, your passport shows "Maria Silva Santos" but your birth certificate shows "Maria Santos Silva". (2) Missing middle names — your passport includes all your given names but your visa application only included your first and last name. (3) Hyphenated vs non-hyphenated surnames — your marriage certificate shows "Garcia-Lopez" but your passport shows "Garcia Lopez" without the hyphen. (4) Initials vs full names — your bank statement or employment contract uses "M. Silva" but your passport shows "Maria Silva". (5) Transliteration differences for names from non-Latin scripts — for example, your Russian passport was transliterated as "Sergey" but your Portuguese visa shows "Sergei". (6) Post-marriage surname changes not reflected consistently — you changed your surname after marriage but some documents still show your maiden name. Any of these discrepancies can trigger AIMA to flag your application for identity verification, which can delay processing or result in a request for corrected documents.
Why is AIMA issuing this warning now?
AIMA issued this formal guidance in July 2026 because name discrepancies have become a recurring source of application delays and rejections as AIMA has digitized its application processes and implemented stricter identity verification protocols. When AIMA's online renewal portal and digital application systems cross-check your name across multiple databases — your visa record, your prior residence permit, your tax authority (Finanças) record, your Social Security record — any mismatch triggers an automatic flag for manual review.

AIMA is now proactively warning applicants to verify name consistency before submission to reduce delays and administrative burden on both applicants and AIMA staff.
Who is most at risk for name discrepancies?
Applicants with compound surnames (common in Spanish-speaking and Portuguese-speaking countries, where people use both their father's and mother's surnames), hyphenated names (common after marriage in many countries), matronymic or patronymic naming conventions (common in Iceland, parts of the Middle East, and some African countries), or names that use non-Latin scripts (Russian, Arabic, Chinese, Japanese, Korean, etc.) are most at risk. These naming conventions can lead to inconsistencies when documents are issued by different countries or translated into Portuguese. For example, a Brazilian applicant named "João Silva Santos" may have their surname recorded as "Santos" on some documents and "Silva Santos" on others. A Russian applicant named Сергей may be transliterated as "Sergey", "Sergei", or "Serguei" depending on which country issued the document. AIMA's systems may flag these variations as discrepancies even though they refer to the same person.
How do I check my documents for name consistency?
Gather all documents you plan to submit with your AIMA application: passport, Portuguese residence visa, birth certificate, marriage certificate (if applicable), employment contract, bank statements, rental contract, Portuguese tax registration (NIF), Social Security registration (NISS), and any other supporting documents. For each document, write down exactly how your full name appears — including the order of your given names and surnames, whether middle names are included or omitted, and whether surnames are hyphenated or separated. Compare all the name variations. If your name appears identically on every document, you are clear. If you find discrepancies — even minor ones like a missing middle name or a different surname order — you need to address them before submitting your application. Pay special attention to your passport vs your Portuguese visa, as this is the most critical name match AIMA will verify.
What should I do if I find a name discrepancy?
If the discrepancy is on a document you control — such as an employment contract, rental contract, or bank statement — contact the issuing party (your employer, landlord, or bank) and request a corrected version with your name spelled exactly as it appears on your passport. If the discrepancy is on an official government document such as your birth certificate, marriage certificate, or Portuguese visa, the solution is more complex. For birth or marriage certificates, you may need to obtain a certified translation or apostilled copy that matches your passport. For Portuguese visa discrepancies, you may need to contact the Portuguese consulate that issued your visa and request a correction, though this is often not possible after the visa has already been issued.
