About Sterna Lawyers

Editorial summary

Sterna Abogados is a Madrid-founded immigration practice led by ICAM lawyer Ainhoa Manero. Founded in 2013, it publishes offices in Madrid, Valencia and Mexico City and an eleven-person team. Its current services cover residence, work, study, digital-nomad, nationality and regularisation matters for individuals and employers.

Sterna Abogados is a specialist immigration practice founded by Ainhoa Manero in 2013. Its current official team page lists eleven professionals, including Ainhoa as managing partner and founder, Daniela Jerez Arias as head of legal, and Marta Millán Fernández and Andrés Fermín Sosa as lawyers, alongside specialists in mobility, legal operations, expansion, translation and finance. The firm publishes offices in Madrid and Valencia, plus a Mexico City office supporting cross-border clients. It advises individuals and companies on Spain's non-lucrative and digital-nomad routes, work and student permissions, long-term and family residence, Spanish nationality, arraigo and other regularisation procedures. Ainhoa's official profile identifies her as a member of the Madrid Bar (ICAM), and a firm-published legal article displays membership number 94190. Sterna's official material says matters are managed by a dedicated immigration lawyer and that Spanish and English are available; additional team languages include Portuguese, French and Russian. Spain's Golden Visa ended for new applications on 3 April 2025. One current Sterna Valencia page still carries a legacy Golden Visa reference; that superseded service claim is disclosed and excluded from this profile.
