Applying for a work visa in Spain requires submitting documents that Spanish authorities can read, verify, and accept as legally valid. For documents issued in another language, that means certified translation. Not a bilingual summary, not an AI-generated draft, but a translation with a formal declaration of accuracy that meets the standards set by Spanish consular and immigration authorities.
Which documents require certified translation
The specific list depends on the visa category, but the documents most commonly required for a Spanish work visa include:
- Criminal record certificate: issued by the relevant authority in the applicant's country of origin and translated into Spanish
- Academic degree or diploma: required for visas tied to professional qualifications
- Employment contract: when issued in another language by a Spanish employer or an entity based abroad
- Birth or marriage certificate: needed for family reunification linked to the visa
- Medical certificates: depending on the visa type and sector
- Diploma supplement: relevant for qualification recognition procedures
The receiving authority determines the exact list. Before commissioning any translation, confirm the requirements directly with the relevant Spanish consulate or the Dirección General de Migraciones.
Certified, sworn, or simple: understanding the difference
The terminology matters. Using the wrong type of translation is one of the most common reasons visa applications are delayed or rejected.
Simple translation: produced by a translator with no formal declaration attached. It has no legal standing for consular or administrative purposes.
Certified translation: accompanied by a signed declaration from the translator or translation company attesting to the accuracy and completeness of the translation relative to the source document. This is the standard format accepted by most consulates and public authorities for immigration purposes.
Sworn translation (traducción jurada): in Spain, this is carried out by a sworn translator-interpreter officially appointed by the Spanish Ministerio de Asuntos Exteriores. Some public authorities in Spain require this specific format for certain document types. If the receiving authority specifies *traducción jurada*, a certified translation from a non-appointed translator will not suffice.
For work visa applications, the practical rule is this: if a document is going directly to a Spanish public authority, confirm whether they accept certified translation from an ISO 17100-certified company or require a sworn translation. When in doubt, opt for the higher standard.
Apostille and legalisation: what applies between Portugal and Spain
Both Portugal and Spain are contracting parties to the Hague Apostille Convention. This means Portuguese public documents destined for Spain can be apostilled rather than going through full consular legalisation.
The apostille and the certified translation are separate requirements. The apostille authenticates the origin of the document; the certified translation makes its content accessible to Spanish-speaking authorities. Both may be required at the same time.
To apostille a Portuguese document, the applicant submits a request to the relevant district court or the Portuguese Ministry of Foreign Affairs, depending on the document type. The certified translation can be ordered in parallel, before the apostille is returned, provided the translator works from a clear scanned copy of the original. This saves time in tight-deadline situations.
For documents originating in other countries, the same logic applies: confirm whether that country is a party to the Apostille Convention and what the Spanish consulate accepts before proceeding.
How to prepare without delays
Visa processing timelines are unforgiving. A document returned for incorrect translation format can push a start date back by weeks. Some practical steps:
- Request source documents early. Criminal record certificates have short validity periods and may need to be ordered well in advance.
- Confirm the exact requirements with the consulate before commissioning the translation. Requirements can differ between visa categories and between individual consulates.
- Order apostilles and translations in parallel where possible. There is no need to wait for one to complete before starting the other.
- Keep certified copies of translated documents. The same translations may be needed later for employer records, social security registration, or municipal registration in Spain.
The quality of translation in a visa application has direct consequences. Errors in terminology, formatting inconsistencies, or missing declarations can result in rejection at the point of submission.

Frequently Asked Questions
What documents need certified translation for a Spanish work visa?
The most common documents include criminal record certificates, academic degrees or diplomas, employment contracts, birth or marriage certificates, and medical certificates. The exact list depends on the visa category and should be confirmed with the relevant Spanish consulate.
Is certified translation from a translation company accepted by Spanish authorities?
For most work visa categories, certified translation from an accredited company accompanied by a formal declaration of accuracy is accepted. In specific cases, Spanish authorities may require a traducción jurada carried out by a sworn translator-interpreter appointed by the Spanish Ministry of Foreign Affairs. Always confirm the requirement with the receiving authority before ordering.
Do I need an apostille before getting a certified translation?
No. The apostille and the certified translation are separate processes and can be handled in parallel. Both Portugal and Spain are parties to the Hague Apostille Convention, so documents exchanged between the two countries can be apostilled rather than going through consular legalisation, but the apostille does not replace the translation.
What is the difference between a certified translation and a sworn translation in Spain?
A certified translation carries a signed declaration of accuracy from the translator or company. A sworn translation (traducción jurada) in Spain must be carried out by a translator-interpreter officially appointed by the Spanish Ministry of Foreign Affairs. Some Spanish public authorities require the sworn format specifically for certain document types.
How long does certified translation of visa documents take?
Individual documents such as certificates or diplomas are typically translated within 2 to 5 business days. For urgent requirements, contact the translation company directly to check availability of expedited delivery.
