Spain has introduced an important change for international students who want to pursue a PhD. Since August 2026, a new administrative criterion clarifies that foreign PhD candidates must apply for the national residence permit for research, processed through the Large Companies and Strategic Groups Unit (UGE-CE).
This update involves much more than a change in the way an application is submitted. The residence permit for researchers offers significant advantages compared with the traditional student stay permit, especially in terms of processing times, family members’ rights and the possibility of accumulating legal residence for a future Spanish nationality application.
For those considering pursuing a PhD in Spain, and for universities seeking to attract international talent, understanding this new immigration route is essential.
What has changed for international PhD students in Spain?
Until recently, it was common for foreign PhD candidates to apply for a student stay permit in order to carry out their research at Spanish universities.
Although the residence permit for researchers already existed, many academic institutions used the student route because they were more familiar with the procedure or considered it simpler from a documentary point of view.
However, this approach was not always the most beneficial for researchers.
On 11 August 2026, the Directorate-General for Migration Management published Management Criterion 2/2026, clarifying the application of the national residence permit for research to foreign nationals enrolled in PhD programmes.
The criterion recognises that PhD candidates carry out research activity and establishes that they fall within the residence permit provided for in Article 72 of Law 14/2013.
Under this criterion, the student stay permit is no longer the applicable route for foreign nationals who are going to pursue a PhD in Spain. These cases must be processed through the national residence permit for research.
Therefore, this is not simply a matter of choosing between two immigration options. The new criterion determines which authorisation applies to international PhD students.
This allows PhD candidates to obtain a residence permit instead of being limited to a student stay permit.
What is the residence permit for researchers in Spain?
The residence permit for researchers is an authorisation aimed at non-EU nationals who wish to carry out research, training, development or innovation activities in public or private entities established in Spain.
It is regulated under Article 72 of Law 14/2013 and is processed through the Large Companies and Strategic Groups Unit (UGE-CE).
This authorisation allows the holder to reside and work legally in Spain in order to carry out the relevant research activity.
Under the new criterion introduced in August 2026, students enrolled in PhD programmes are expressly included within the national residence permit for research.
The distinction is important because this is not simply a permit to attend classes. A PhD candidate carries out a research project, generates knowledge and contributes to the scientific activity of the host institution.
The new immigration classification reflects this reality.
Five advantages of the residence permit for researchers compared with the student stay permit
1. Decision within a maximum period of 20 working days
One of the main advantages is the speed of the procedure.
Applications for residence permits for researchers processed by the UGE-CE have a maximum decision period of 20 working days.
This represents an important advantage for researchers who need to organise their move to Spain, particularly when they must coordinate the start of their PhD, accommodation and the arrival of their family members.
However, this is the legally established maximum period for issuing a decision and does not constitute a guarantee of automatic approval.
2. It is a residence permit, not a student stay permit
This difference may have significant long-term consequences.
The residence permit for researchers constitutes legal residence in Spain.
By contrast, the student stay permit has a different legal nature and does not automatically produce the same effects for all immigration procedures.
This is particularly relevant for those who wish to remain in Spain for several years and eventually apply for long-term residence or Spanish nationality.
For this reason, the applicable immigration route should be analysed not only in light of the duration of the PhD, but also with regard to the applicant’s longer-term personal objectives.
3. Family members can accompany the researcher and work
One of the most important advantages for international PhD candidates is the possibility of relocating to Spain with their family.
The residence permit for researchers allows applications to be submitted for certain family members, provided the relevant requirements are met.
These may include the spouse or partner and children who meet the conditions established by law.
In addition, family members who obtain a residence permit linked to that of the researcher may access the Spanish labour market.
This means that the spouse or partner may work as an employee or carry out a self-employed activity, without relying exclusively on the researcher’s income.
For many PhD candidates, who are at a professional stage in which they already have family responsibilities, this possibility can be a decisive factor when choosing Spain as an academic destination.
An additional advantage for children: access to university fees linked to residence status
Residence status may also have financial consequences for the researcher’s children when they access university studies in Spain.
In certain universities and autonomous communities, non-EU foreign students who do not have resident status may be subject to higher tuition fees.
Therefore, if the children of the PhD candidate hold a residence permit, they may, where applicable, be able to access the public tuition fees applicable to resident students instead of the higher fees established for certain non-resident foreign students.
This advantage will depend on the university, the autonomous community, the type of studies and the student’s individual circumstances, so each case should be assessed separately.
4. Possibility of working during the PhD
The residence permit for researchers authorises the holder to carry out the research activity on which the permit is based.
This provides an appropriate immigration framework for the scientific activity carried out during the PhD.
Where the researcher wishes to undertake other professional activities, it will be necessary to assess their compatibility with the residence permit and with the relevant academic or contractual obligations.
The main advantage is that the authorisation expressly recognises the research and professional dimension of the PhD.
5. Residence may count towards an application for Spanish nationality
This is one of the aspects that may generate the greatest interest among international researchers.
As a general rule, in order to apply for Spanish nationality by residence, the applicant must have resided in Spain legally, continuously and immediately prior to the application for the relevant required period.
The general period is ten years, although shorter periods apply in certain cases.
For example, nationals by origin of Ibero-American countries may apply for Spanish nationality after two years of legal residence, provided they meet the remaining requirements.
The residence permit for researchers may be particularly beneficial because it constitutes legal residence for these purposes, unlike the student stay permit.
There is also another reduced residence period that may be relevant for some PhD candidates: individuals who have been married to a Spanish citizen for at least one year and are not legally or de facto separated may apply for Spanish nationality after one year of legal residence in Spain, provided they meet the other legal requirements.
This does not mean that Spanish nationality is granted automatically after one, two or ten years, depending on the applicable case. The applicant must also comply with the requirements concerning continuity of residence, good civic conduct, integration and any other legally required conditions.
How to apply for the residence permit for researchers if you are going to pursue a PhD
The procedure is processed electronically through the UGE-CE.
The applicant must prove, among other matters, their identity, academic situation and connection with the PhD programme and the relevant institution.
The specific documentation will depend on the researcher’s individual circumstances and the applicable route.
An important feature is that, when the PhD candidate does not have an employment contract with the research entity, they may submit the application personally in accordance with the official instructions.
In other cases, the application may be submitted by the university, research entity or its duly authorised representative.
Therefore, before starting the procedure, it is advisable to coordinate with the university regarding both the required documentation and the identification of the person or entity authorised to submit the application.
What documentation must the university provide?
For universities and research centres, managing this procedure may be simpler than it might initially appear.
In addition to the documentation related to the PhD programme and the researcher’s connection with the institution, the university must provide the documents necessary to properly evidence its own legal and institutional status.
The documentation that may be required from the institution can include corporate or constitutive documents and certain tax-related documentation.
In any case, the specific documents must be reviewed according to the university, the PhD candidate’s circumstances and the route used to process the residence permit.
Proper coordination between the researcher, the university and the professional managing the case can help avoid subsequent requests for additional documentation and streamline the filing before the UGE-CE.
What does this change mean for Spanish universities?
The update also represents an opportunity for universities and research centres seeking to attract international talent.
The choice of a PhD programme does not depend exclusively on academic quality or research opportunities.
For many international candidates, immigration processing times, the possibility of relocating with their family and the professional opportunities available to their partners are also decisive factors.
Having access to a residence route that takes these aspects into account may make Spain more attractive compared with other academic destinations.
From an international mobility perspective, universities can use this change as an opportunity to review their procedures for onboarding foreign PhD candidates.
It is particularly important that admissions departments, human resources teams and international relations offices understand the new administrative interpretation and properly coordinate the required documentation.
The procedure can be carried out electronically, but the application must be correctly prepared and the appropriate route and documentation must be identified in each individual case.
What happens if I already have a student stay permit for my PhD?
PhD candidates who are already in Spain with a student stay permit should assess their individual circumstances before making any changes.
The new administrative criterion does not mean that all previously granted student stay permits are automatically converted into residence permits for researchers.
It will be necessary to review the current authorisation, the applicant’s academic situation and the available options for applying for the relevant residence permit.
This is particularly important where the researcher wishes to plan their long-term residence in Spain, bring family members to Spain or consider a future application for Spanish nationality.
Planning a PhD also means planning your residence in Spain
Pursuing a PhD abroad is an important academic and personal decision.
However, it also involves making immigration decisions that may affect the researcher and their family for several years.
The new criterion introduced in August 2026 provides a more appropriate immigration framework for foreign PhD candidates under the residence system for researchers and highlights the advantages offered by this authorisation.
For future PhD candidates, the recommendation is to assess their immigration strategy before beginning the relocation process.
For universities, it is equally important to incorporate this update into their procedures for welcoming and recruiting international research talent.
