How to Prove the 3-Year Professional Experience Requirement for Spain's Digital Nomad Visa

Spain's international teleworker rules are contained in Law 14/2013. For the qualification requirement, the applicant can rely on a graduate or postgraduate credential from an institution of recognised standing, or prove a minimum of three years of professional experience.

The degree and the experience route are alternatives. The law does not say that professional experience is available only in exceptional cases, and an applicant should not be treated as automatically weaker merely because the application relies on experience instead of a degree.

The experience should be relevant to the remote activity

Official consular guidance describes the experience as connected with the professional activity concerned. The evidence should make it possible to understand why the applicant's previous work qualifies them for the remote role they will perform while living in Spain.

This does not necessarily require the same job title in every document. A person may have worked as a software engineer, backend developer and technical consultant while performing substantially similar functions. The underlying work matters more than identical wording.

Regulated professions may create an additional issue

For many remote professions, such as software development, marketing, design or business consulting, there is no separate Spanish professional licence. A regulated profession can be different. Recognition or authorisation to practise may be needed independently of proving three years of experience.

Neither the law nor the general official guidance publishes a closed list saying that applicants must use specific documents such as SA302, IRS transcripts, client letters, invoices or a government employment-history report.

This is partly unavoidable. Countries record work differently. A British freelancer may have Self Assessment records. A US contractor may have Schedule C and Forms 1099. A platform worker may have earning statements and client histories that do not exist in a traditional employment relationship.

The absence of a checklist does not mean every document has equal weight. It means the evidence must be assessed according to what it actually proves.

A useful way to prepare the file is to stop thinking only in terms of document names and start thinking in terms of questions. Each important question should have an answer supported by evidence.

There is rarely one perfect document

An official tax record may strongly support that income was declared during certain years but say little about the work. A detailed client letter may explain the work but be weaker evidence of payment. A contract may show what the parties intended, while invoices and bank records help show that the relationship operated in practice.

The strongest package is not necessarily the largest. It is the package in which different documents answer different questions without contradicting each other.

The following table is practical guidance, not an official UGE ranking. The value of each document depends on its detail, authenticity, date range and relationship with the rest of the application.

Some records are useful for explaining the professional history but should rarely be the foundation of the package on their own.

• CV or résumé;
• LinkedIn profile;
• personal website;
• portfolio;
• GitHub history;
• published work;
• professional references;
• email correspondence;
• project completion records;
• Upwork or other freelance-platform history.

These records may help connect the evidence, explain job-title changes and show the type of work performed. Self-created profiles generally provide weaker independent verification than employer, client, tax or government records.

CV, LinkedIn and portfolio

A CV provides a map of the professional history, but the applicant creates it. LinkedIn can support consistency but is not an official employment record. A portfolio can demonstrate skills and projects but may not establish dates, payment, client identity or three years of continuous activity.

Invoices

Invoices are useful timeline evidence, particularly for freelancers. But a self-issued invoice does not necessarily prove that the client accepted the work or paid it. Representative invoices are stronger when matched with contracts, client letters, tax records and payment entries.

Employees often have a simpler evidence structure because one or two employers may cover the full period. A detailed employer certificate is particularly useful when it confirms both duration and professional functions.

Example employee evidence package

1. Detailed employer certificate covering the relevant period.
2. Employment contract and important amendments.
3. Official employment or Social Security history, where available.
4. Payslips, annual tax records or payroll summaries.
5. CV connecting the documents into one timeline.

This is an example of a coherent package, not an official mandatory checklist.

What an employer certificate should ideally include

• the company's full legal name and address;
• the employee's full name;
• start and end dates, or confirmation that employment continues;
• job title;
• a practical description of duties;
• full-time or part-time status where relevant;
• the signer's name, position and contact details;
• date of issue and signature.

Why the description of duties matters

A letter saying only that a person worked for the company from 2021 to 2024 proves a period but says little about the profession. A better certificate explains the applicant's actual responsibilities and makes the connection with the current remote role visible.

Freelancers face a different problem. No single employer may be able to confirm the full three-year period, and the applicant may have worked for several clients, through platforms or under short contracts.

A freelancer therefore often needs several documents because no one record performs the same function as a detailed long-term employer certificate.

Example freelancer evidence package

1. Tax returns or official tax summaries covering the relevant years.
2. Client contracts and statements of work.
3. Client confirmation letters.
4. Representative invoices from the relevant periods.
5. Bank, PayPal, Wise, Stripe or platform payment records.
6. Accountant confirmation where it adds useful independent context.
7. Portfolio or project records explaining the nature of the work.
8. CV and a concise professional timeline.

Proving existence, duration, duties and real activity

Tax registration, returns and platform records can show that the activity existed. Dated contracts, invoices and client letters can establish duration. Statements of work and detailed confirmations explain the services. Payments, declared income and completed projects support that the activity was real.

There is no official universal UGE template. The purpose of the letter is to fill evidence gaps, not to use formal language for its own sake.

• full legal name of the employer or client;
• applicant's full name;
• start and end dates;
• job title or type of services;
• description of duties or deliverables;
• whether the work was ongoing or project-based;
• confirmation that the work was actually performed;
• signer's name, position and contact details;
• date and signature.

Example wording

The wording should be true and tailored to the actual relationship. A generic template can create inconsistencies with the contract, invoices or current role.

UK applicants frequently ask whether SA302 is enough. The accurate answer is that SA302 can be valuable evidence, but no published official rule says that SA302 alone automatically proves three years of relevant professional experience.

HMRC records that may be useful

• SA302 tax calculations;
• Tax Year Overviews;
• Self Assessment tax returns;
• PAYE employment records;
• National Insurance records where relevant;
• VAT registration records;
• Companies House records for owners or directors.

What SA302 can and cannot show

SA302 can support the tax-year timeline, declared income and the existence of self-employed income. It normally does not explain detailed duties, identify every client or show why the work is relevant to the current remote role. Those gaps can be covered with contracts, invoices, client letters and project descriptions.

Example UK freelancer package

• SA302 and Tax Year Overviews;
• client contracts;
• representative invoices;
• client confirmation letters;
• bank or platform payment records;
• a CV and three-year timeline.

US applicants may have a mixture of employee and contractor records. Use tax and payroll records for independent verification and add documents explaining the actual work.

Records that may be useful

• IRS tax transcripts and federal tax returns;
• Schedule C;
• Form 1099-NEC and other relevant Forms 1099;
• Form W-2;
• state tax records;
• business registration records;
• employment verification letters;
• client contracts, invoices and payments.

These records may establish declared professional income and the years in which activity existed. Their main limitation is that they may say little about the services performed. Detailed letters, statements of work or project records can connect the tax evidence with the qualification requirement.

Yes. The rules do not state that the entire three-year period must be proved by one document, one employer or one client. A combined package is often the only realistic way to document freelance or mixed professional histories.

Mixed experience and overlapping clients

An applicant may combine employee and freelance periods if the work is relevant and documented. However, working for three clients during the same six months does not create 18 months of experience. Time should be counted chronologically.

Continuity

The official rule requires a minimum of three years of professional experience but does not expressly state that the period must be uninterrupted. An applicant with a career break should show the break honestly and demonstrate that the total relevant experience still reaches three years.

Different employers or clients

The experience does not have to come from one organisation. What matters is whether the combined periods demonstrate the required professional background.

Older experience

No general official rule says that the full period must fall within the last three years. Older experience may still count. If the applicant left the profession for a long period or changed to an unrelated field, the connection with the current remote activity may need a stronger explanation.

Many Digital Nomad Visa explanations mix three separate periods. They should be treated as different evidence questions.

Not every document in the package requires or can receive an apostille. The first question is whether the document is public or private under the law of the issuing country.

Foreign public documents

Government tax certificates, official employment records, professional registration certificates, public diplomas and notarial documents may require an apostille or diplomatic legalisation to produce effects in Spain, subject to treaties and exceptions.

Private documents

Client letters, private employment letters, commercial contracts, invoices and platform reports are not automatically public documents. They cannot always be sent directly for an apostille.

Where formal authentication is required, a signature may first need to be notarised. The resulting notarial act may then be eligible for an apostille. The precise route depends on the issuing country.

Do not notarise everything automatically

Notarising and apostilling every invoice can be expensive and may add little value. Identify which documents are central, which are public and what the relevant consulate or filing route requires.

Documents issued in another language will generally need a Spanish translation. Translation and apostille are different procedures: an apostille authenticates a public document or signature, while a translation makes the content understandable in Spanish.

An apostilled document may still need translation, including the apostille itself. Depending on the document and filing route, a sworn translation by an authorised translator may be required.

Step 1: list every relevant period

Create a simple table before collecting documents. Include the employer or client, role, duties, dates and evidence available.

Step 2: calculate chronological experience

Count calendar time rather than adding simultaneous clients. Two clients served during the same 12 months still represent 12 months of chronological experience.

Step 3: identify unsupported periods

Mark periods where you have a contract but no evidence of performance, tax records but no explanation of duties, or invoices without matching payments or client confirmation.

Step 4: add documents that answer the missing question

Use letters to explain duties, payments and tax records to support actual activity, and contracts or statements of work to define the relationship.

Step 5: resolve contradictions

Check dates, company names, job titles, currencies, employee or contractor status and the spelling of the applicant's name. If differences are legitimate, explain them briefly.

Step 6: prepare a short document index

A one- or two-page cover table can identify which documents prove each period. The explanation should help the reviewer navigate the evidence, not replace missing evidence with a narrative.

Employee with one long-term employer

• employer certificate covering four years;
• employment contract;
• official employment history;
• selected payslips and tax records;
• CV.

Freelancer with several clients

• tax returns covering three years;
• client letters and service contracts;
• representative invoices;
• bank payments;
• professional timeline.

Freelancer using Upwork

• Upwork work history and earning reports;
• tax records;
• selected contracts and statements of work;
• platform payout records;
• client confirmations and portfolio.

Mixed employee and freelance experience

Eighteen months of employment and twenty-four months of freelance work may form one qualifying history if the periods are relevant, properly documented and not double-counted.

Older experience plus current work

Earlier relevant employment can be supported by past certificates and tax records, while the current contract and a short explanation connect that experience with the present role.

1. Submitting only a CV or LinkedIn profile.
2. Showing income without explaining the work.
3. Showing contracts without evidence that the activity occurred.
4. Confusing the three-year rule with the three-month relationship.
5. Counting simultaneous clients as extra calendar years.
6. Using inconsistent dates or company names without explanation.
7. Assuming different job titles automatically mean different professions.
8. Assuming SA302, Schedule C or one tax return is automatically sufficient.
9. Calling a private letter an official government certificate.
10. Apostilling every private document without checking the requirement.
11. Forgetting Spanish translations.
12. Uploading hundreds of documents without an index.
13. Presenting an online success story as if it were an official UGE rule.

Official pages can change, and a consulate may publish additional local instructions. Always check the current source for the route and country from which you are applying.
