My son doesn’t have residency in Spain but has lived here…

Answer: I am so sorry to hear about this.

Spain is one of the most welcoming European countries and as a member of the European Union, it offers specific facilities to citizens of other member states who want to relocate here. EU citizens do not need a visa when moving to Spain as they are only required to register with the local police office in the city they will reside.

Non-EU citizens, on the other hand, are required to complete various formalities that allow them to obtain temporary residence and then a permanent residency in Spain. Here are the main types of visas which lead to obtaining a permanent residence permit in this country:

1. employment visas which is one of the safest ways to obtain permanent residency in this country;
2. student visas based on which foreign students can relocate to Spain temporarily and then permanently;
3. non-lucrative visas which are available for foreigners seeking to retire to Spain provided that they have sufficient financial means to support themselves;
4. investment visas which are available foreign entrepreneurs and high net worth individuals immigrating to Spain.
