Hello Gallardo,

Initially, your suggestion will work in terms if residency if you can access a student visa based on your Spanish College inscription. However, the residency period of student visa holders is not recognized for the residency requirement of the Nationality application( it was not long time ago, but no more )

After two years holding a residence status, that is not recognized to student visa holders, you will be able to apply for the Spanish Nationality. This means that while you hold a student residence card, you will have to look for a job and then modify your card to a salaried or self-employed work and residence permit and then apply for the Nationality after two years.

Regards,
