If you are coming to Spain on a study visa or a non-lucrative residence visa, health insurance is not one more formality: it is a requirement of the application. Spain requires health insurance taken out with an insurer authorised to operate in Spain, and the social security agreement between Mexico and Spain does not replace it.
Why it is compulsory
The immigration regulation in force (Royal Decree 1155/2024) includes health insurance among the requirements for both visas:
- Study visa. Article 35.i requires health insurance arranged with an insurance company authorised to operate in Spain, with benefits similar to those of the basic common portfolio of healthcare services of the National Health System, and valid for the whole of the intended stay.
- Non-lucrative residence. Article 61.2.b likewise requires health insurance.
The reason is simple. The Law on the cohesion and quality of the National Health System grants publicly funded access to healthcare to foreign nationals with legal and habitual residence who are not required to prove health cover by another route (article 3.2.c of Law 16/2003). A student is in a situation of stay, not of residence, and someone residing without gainful activity must prove cover by another route: in both cases, the cover is the insurance submitted with the application, not the public health system.
What the policy must satisfy
Beyond what the regulation says, the Consulate General of Spain in Mexico publishes the criteria it applies when reviewing insurance. As at September 2026, for the study visa it requires the insurance to cover the whole period of stay and all types of healthcare without limitations, with no co-payments, waiting periods or deductibles, taken out with an insurer authorised to operate in Spain, and the insurance certificate to be submitted together with proof of payment. For non-lucrative residence it requires the insurance to cover all the risks covered by the public health system in Spain.
In short, before taking out a policy it is worth checking four points:
- That the insurer is authorised to operate in Spain.
- That it covers medical, hospital and emergency expenses with cover equivalent to that of the Spanish public health system.
- That it has no co-payments, waiting periods or deductibles (the consulate requires this expressly for the study visa).
- That it covers the whole duration of the authorised stay.
In our experience, a policy failing any of these conditions is usually a ground for refusal or delay of the visa application. It is a mistake avoided by reading the general conditions before signing, not afterwards.
What the Mexico-Spain agreement does not give you
People often think the bilateral social security agreement between the two countries resolves medical cover. It does not. The agreement, signed in Madrid on 25 April 1994 and in force since 1 January 1995, is limited to pensions: in Spain, those arising from accidents at work and occupational diseases, and those for invalidity, old age, death and survivorship (article 2). Its main effect is that, where needed to qualify for a pension, contribution periods in both countries are added together (article 7).
So:
- It does not include healthcare: it gives no right to medical treatment in Spain.
- It does not replace the health insurance required for a study or residence visa.
- It is different from the special healthcare agreement, a Spanish domestic route into the public health system in exchange for a fee, which requires registration on the padrón and proof of one year of continuous actual residence in Spain, among other requirements (article 3 of Royal Decree 576/2013). It is not an option on arrival.
If you start working while studying
The stay authorisation for higher education allows you to work under certain conditions. When you carry out work under that authorisation, the health insurance requirement is treated as met by your registration with the corresponding social security scheme (article 57.5 of Royal Decree 1155/2024). Until then, private insurance is what covers you.
Our recommendation
In our experience, it is better to take out the insurance directly with an insurer authorised to operate in Spain, rather than through third-party packages whose conditions are not always clear. A badly chosen policy, with co-payments or waiting periods not spotted in time, can delay or complicate the visa application. Read the general conditions, check each of the four points above, and keep the certificate and proof of payment: you will need them at renewal too.
