Not every language course gives grounds for a visa
The difference isn't whether a course is "good" or "bad", but whether the law recognises it as grounds for an estancia por estudios. For language courses the rule is narrow: programmes at official language schools (escuelas oficiales de idiomas, which are state-run) or at private centres accredited by the Instituto Cervantes (or an equivalent body — for Catalan, Basque or Galician) qualify. Simply "teaching Spanish" doesn't make a school valid grounds for a visa — if the centre isn't on this list, no enrolment certificate from it will help.
Where the Instituto Cervantes comes in — and where it doesn't
Instituto Cervantes accreditation (SACIC) is first and foremost a mark of quality: it checks how the school is organised, its teaching materials, additional services and information policy, and it's confirmed periodically through repeat audits. It wasn't originally a "visa" tool — historically the system is better known in connection with preparing for the DELE exam. But for language courses specifically, the same accreditation also signals that the institution qualifies as grounds for a student visa — this isn't a myth or an agency exaggeration but a direct requirement set out in the official guide of Spain's Ministry of Labour and Migration.
The practical conclusion: since the accreditation is needed for exactly this purpose, you should check it not by what the school says on its website but directly in the Instituto Cervantes' public register — the accreditation may have expired or not yet been confirmed for a new period, and "we're accredited" on the school's site may have been true a year ago.
Not sure where to start?
A short two-minute quiz: based on your answers, we'll map out your route — what to do next and in what order.
Take the quizHow many hours a week the programme should have
The benchmark that consulates and schools often cite is at least 20 hours of in-person classes per week. But note that in the Ministry's official guidance (August 2025), the 20-hour threshold is given for university programmes, while for language courses the workload is set by the study plan. So 20 hours is a safe practical standard rather than a rigid rule. Another official condition: the language you study must differ from your native language and from the official language of your country of nationality. In practice this doesn't change the substance: if a school offers a course with a lighter workload and calls it "intensive", ask exactly how many 60-minute hours make up a week — some schools structure their packages differently from what the marketing description suggests.
What course length makes sense for a national visa at all
The D visa is designed for stays longer than 90 days — this isn't a formality but the lower limit. A course shorter than three months formally gives no grounds for a national visa at all: only Schengen logic applies, which doesn't suit long-term study. In practice, schools that work seriously with visa students build programmes of 12 to 48 weeks, and for those who aim to reach B2 and continue studying, they recommend no less than 32–36 weeks. Planning a course that only just exceeds 91 days is risky: if anything shifts in your application timeline, the programme may formally fall short of the threshold. How much margin makes sense for your consulate and application season is a question best settled before paying for the course, not after.
Red flags in offers from schools and agencies
The first and most obvious one is a promise of a "guaranteed visa". The decision is always made by the consulate, and no school or agency can guarantee it; if you're promised this in so many words, that alone is a reason to be wary. The second is pressure to pay quickly with minimal checking of whether you're even a fit for the programme: it's a sign that the course exists primarily as a pretext for a visa rather than as real study — and it's exactly these programmes that the Spanish authorities pay extra attention to.
The third is paying without a written contract or with vague refund terms. There have been documented real cases where a language academy (in Barcelona, in particular) left foreign students without their money and without a visa at the same time. Check the accreditation yourself, before paying, rather than relying on what a sales manager tells you.
What to check before paying for a course
- The school is official (EOI) or has a valid Instituto Cervantes accreditation, checked directly in its register.
- An in-person programme — benchmark of 20+ hours per week, counted in real 60-minute hours.
- The programme is longer than 90 days — with a margin, not cutting it fine.
- There's a written contract with clear payment and refund terms.
- Nobody promises a "guaranteed visa" — the decision always rests with the consulate.
Frequently asked questions
No. Instituto Cervantes accreditation is confirmed periodically and can expire. Check the school's status directly in the Instituto's public register, not by the description on the school's own website.
No — the D visa is designed for stays longer than 90 days. For shorter courses a national visa is formally unavailable, and you need to consider a different type of trip.
The visa decision is made solely by the consulate, and no one can guarantee it in advance. An outright promise of a "guarantee" is a reason to be wary and double-check the rest of that school's or agency's terms.
The in-person format is mandatory, and 20 hours is a widely used practical benchmark: officially, the workload for language courses is set by the study plan. Ask the school how many real 60-minute hours make up the stated workload — intensive packages aren't always counted the same way.
If something in your situation doesn't fit the general pattern, that's normal — visa cases almost always have nuances. and we'll look at it for free and suggest your next step.
