If your visa has ‘no autorizado a trabajar’ (not authorised to work) there is still a way around this. You can do paid ‘work experience’ at a company, as long as the experience is relevant to your studies. E.g. If you are doing a teacher development course, you can work as an English teacher. If you are doing an engineering degree, you can work at an engineering firm.

• Nature of Work: An internship or trainee agreement rather than a formal employment contract.
• Duration: Varies but can last from a few months up to two years.
• Three-Way Agreement: Involves the student, the educational institution, and the company or organisation offering the internship.
• Stipend or Compensation: Not always provided, but many offer some form of compensation or benefits. In some cases it is as high as a regular salary, especially with English teaching.
• Alignment with Studies: The internship should be in line with the student's academic program or course. E.g. If you do a teacher training course, you can work as an English teacher. If you do a Masters in marketing, you can work in a marketing company.

• If your visa has ‘no autorizado’, your employer must obtain authorization from the Servicio Público de Empleo Estatal (Public Employment Service). This ties you to a specific employer and role.
• If your visa has ‘autorizado’, there is no additional paperwork required. You automatically have the right to work.
• The job or internship must not interfere with the primary purpose of your stay: your studies.

• Work authorization lasts for the contract's duration but can't exceed the student visa's length.
• If renewing your student visa, remember to renew work authorization if you intend to continue working.

• All workers, including students, must be registered with the Spanish Social Security system, providing access to healthcare and other benefits.
• Students are also subject to income tax based on earnings. Ensure you understand Spain's tax system to remain compliant.
