Spain Student Visa for a PhD or Research Programme: 2025 Guide

Applying for an estancia por estudios visa for a PhD or research programme in Spain involves the same core visa category as all other student applicants, but the documentation requirements have some important differences. PhD students are enrolled in a doctorado programme or undertaking a defined research stay at a Spanish university or research institute. The consulate needs to understand the nature of your research, your enrollment status, your funding, and your academic supervision — this guide covers all of these elements, including the practical considerations specific to doctoral and research visa applicants.

PhD vs Research Stay: Two Distinct Cases

There are two common scenarios for PhD and research visa applicants:

Full PhD Enrollment (Doctorado)

You are enrolled in a doctorado programme at a Spanish university — a formal multi-year research degree supervised by Spanish academics, leading to a doctoral thesis and the title of Doctor. This is a full student enrollment, covered by the estancia por estudios visa. Annual renewals (prórrogas) are required for the duration of the PhD.

Research Stay or Visiting Researcher

You are a doctoral student at a foreign university undertaking a research stay (estancia de investigación) at a Spanish university or research institute — typically 3–12 months. You are affiliated with the Spanish institution as a visiting researcher and produce documented research output during your stay. This is also covered by the estancia por estudios visa if the stay exceeds 90 days.

Enrollment and Acceptance Documentation

For a full doctorado enrolment, you need the official carta de admisión al programa de doctorado from the Spanish university. This must include:

• Your name as on your passport
• The name of the doctoral programme (Programa de Doctorado)
• Your thesis or research area (or if not yet defined, confirmation of enrollment in the programme)
• Confirmation of supervision arrangement (director de tesis) — name of your Spanish supervisor
• Course duration or expected thesis submission timeframe
• Weekly study/research hours (must be at least 15 hours/week for student visa purposes)
• Institutional stamp and authorised signature

For a research stay, you need an agreement letter (convenio de colaboración or carta de invitación) from the Spanish host institution, confirming the nature of the visit, the host researcher or institution accepting you, and the dates of the stay.

Supervisor Letter and Research Plan

While not universally mandated by the EX-00 form checklist, some consulates — particularly for PhD applications where the nature of the study may be less obvious from the enrollment letter alone — ask for or strongly benefit from:

• A letter from your Spanish doctoral supervisor (director de tesis) confirming the supervision arrangement, research topic, and expected timeline
• A brief research plan or project description (1–2 pages) — not required formally but can help clarify the academic legitimacy of the application for a consular officer unfamiliar with doctoral programmes

These supporting documents cannot hurt your application and may significantly help it. Prepare them in Spanish or with a Spanish translation.

Funding and Financial Requirements for PhD Students

PhD students have several funding scenarios, each with its own financial evidence approach:

Fully Funded PhD Fellowship

If your doctoral programme comes with a stipend from a Spanish funding body (FPU — Formación de Profesorado Universitario; FPI — Formación de Personal Investigador; La Caixa Fellowship; regional funding bodies), present the official award letter specifying the monthly stipend and programme duration. Spanish doctoral fellowships are well-regarded by consulates and typically satisfy the financial requirement in full.

Self-Funded Doctoral Students

Show personal bank statements demonstrating €7,000–€10,000 for the first academic year, or a parental sponsorship letter with supporting financial documents.

Foreign Scholarship / Research Grant

If funded by your home country or a foreign institution (e.g., DAAD, British Council, Fulbright, EU Marie Curie), present the official award letter specifying the monthly amount, duration, and that the funding covers your stay in Spain.

Duration and Annual Renewals for PhD Students

Spanish doctorado programmes typically take 3–5 years. The estancia por estudios visa is issued for one academic year at a time. This means PhD students renew their visa annually at the Spanish extranjería (as a prórroga) for the entire duration of their studies.

At each annual renewal, you need:

• Updated enrollment certificate from the university confirming you are still enrolled in the PhD programme
• RAPI report or DAD informe de seguimiento (annual evaluation report) confirming academic progress — some extranjería offices request this
• Financial evidence for the next year (stipend continuation letter or bank statements)
• Valid health insurance
• Current TIE card

Renewals for PhD students are generally viewed favourably by immigration authorities as long as academic progress is being made and there is a realistic completion timeline.

Research Ethics and Affiliated Institutions

Some PhD and research visa applicants are affiliated with non-university research institutions — CSIC (Consejo Superior de Investigaciones Científicas, Spain's national research council), IEO (Instituto Español de Oceanografía), or similar public research bodies. These institutions can also issue affiliation letters for the estancia por estudios visa in the same way a university would.

Check whether your specific research institution is recognised under Spanish immigration regulations for student visa sponsorship — most established public research bodies are, but private research centres or very small organisations may require additional confirmation from the consulate.
