Request a Free QuoteCertified immigration document translation is a mandatory legal requirement for anyone planning to live, work or study in Portugal. All documents issued in a foreign language must be translated by a recognised translator to be accepted by Portuguese official authorities. Explore our certified translation services and how we ensure legal compliance for every document.
The AIMA (Agency for Integration, Migration and Asylum), which replaced the former SEF in migration management functions, requires that all documents submitted for visa applications, residence permits or family reunification be translated into Portuguese by qualified professionals. With Portugal establishing itself as one of Europe's most sought-after immigration destinations for expats, digital nomads and retirees, the demand for specialised immigration document translation services continues to grow.
M21Global is your trusted partner for immigration document translation in Portugal. With over two decades of experience, native translators specialised in legal and migration terminology, and ISO 17100 certified processes, we deliver accurate translations accepted by all Portuguese official authorities.

Documents requiring translation for immigration
Immigration processes in Portugal require the submission of various official documents, all translated into Portuguese by a certified translator. The most commonly required documents include: birth, marriage and death certificates, criminal record checks, academic diplomas and transcripts, professional qualification certificates, income statements and bank statements, employment contracts, proof of address and health insurance policies.
AIMA and Portuguese courts require these translations to be performed by a recognised translator and, in many cases, certified by a lawyer or with notarial authentication. M21Global ensures that each translation meets all formal requirements for immediate acceptance. See our certified translation services for more information on the certification process.
Incomplete documents or non-compliant translations can significantly delay your immigration process. Our specialised team knows the requirements of each authority and ensures that all documentation is correct on first submission, saving you time and avoiding additional costs from resubmissions.
Visas and residence permits
Portugal offers various types of visas and residence permits, each with specific documentary requirements. The D7 visa (passive income or retirees) requires translated proof of income and health insurance. The D2 visa (entrepreneurial activity) requires business plans and corporate documentation. The D3 visa (highly qualified workers) needs translated and certified diplomas and professional certificates.
The D4 visa (students) requires academic certificates and translated acceptance letters. The D8 visa (digital nomads) requires remote work contracts and proof of income. The Golden Visa involves extensive financial and property documentation. Family reunification requires birth certificates, marriage certificates and other translated civil status documents.
Each visa type has different forms, deadlines and requirements. M21Global knows the documentary requirements of each process in detail, ensuring you receive translations that comply with the specific requirements of your visa type. See our legal translation services for legal documentation projects.
Hague Apostille and document legalisation
The Hague Apostille is a certificate that validates the authenticity of public documents for international use between signatory countries of the Hague Convention. Portugal, as a member of the Convention, accepts apostilled documents without requiring additional consular legalisation, significantly simplifying immigration processes.
For documents from countries that are not members of the Hague Convention, consular legalisation is required: the document must be authenticated by the consulate or embassy of the destination country in the country of origin. This process takes longer but is equally valid before Portuguese authorities.
M21Global guides clients on the correct procedure for each situation — apostille or consular legalisation — and ensures that the certified translation accompanies the duly legalised document, forming a complete documentary package ready for submission to AIMA, courts or civil registry offices.

Portuguese nationality through translation
Citizens applying for Portuguese nationality — whether by descent, marriage or naturalisation — need to submit translated and certified documentation to the IRN (Institute of Registries and Notaries) and civil registry offices. Documentary requirements vary according to the route of nationality acquisition.
For citizenship by descent (children or grandchildren of Portuguese citizens), birth certificates for the entire family line are required, certified and translated. For citizenship by marriage, marriage certificates and proof of connection to the Portuguese community are needed. For naturalisation, the file includes criminal records, proof of residence and evidence of Portuguese language knowledge.
The IRN is particularly demanding regarding the quality and compliance of submitted translations. M21Global has extensive experience with nationality processes, knowing the specific requirements of each registry office. Our legal translation services cover all documentation required for Portuguese nationality processes.
Quality and security in immigration documents
Immigration documents contain sensitive personal data — identification numbers, financial information, health data and criminal records. M21Global handles this information with the utmost rigour, fully complying with GDPR (General Data Protection Regulation) and maintaining security protocols at all stages of the translation process.
Our processes are certified according to ISO 17100, meaning each translation goes through an audited workflow with a clear separation of roles between translator and reviewer. We sign project-specific NDAs upon request, providing additional contractual confidentiality.
We understand that immigration processes have strict legal deadlines — an expiring residence permit, an AIMA response deadline, a court hearing date. M21Global commits to clear delivery deadlines and meets them consistently, because we understand that a translation delay can mean missing a legal deadline. See our Zero Errors, Total Satisfaction commitment to learn about our quality guarantees.
