SA (Sociedad Anónima) and SRL (Sociedad de Responsabilidad Limitada) are the standard structures. CUIT, IGJ registration, and AFIP tax registration follow.

GBC (Global Business Company) and Domestic Companies are the standard structures. Substance requirements following OECD reforms must be considered; the GBC framework has evolved materially.

OÜ (private limited) is the standard structure, formed online via e-Residency or in person. Reporting obligations are real but proportionate; accounting partners are widely available.

SL (Sociedad Limitada) is the standard private company. Registration involves NIE / NIF, notary, mercantile registry, and tax registration. Spanish tax residency triggers worldwide income reporting; the Beckham Law (special tax regime) may apply to eligible relocated workers.

Residency unlocks personal banking. Forex controls and currency volatility are part of the landscape; multi-jurisdiction structuring is common.

Local banks support resident and corporate accounts; KYC and source-of-funds requirements are real. Bordercase coordinates banking introductions.

Estonian banks have tightened KYC for non-resident e-residents; many international founders rely on EMIs (Wise, Revolut Business, Payoneer, etc.) for day-to-day banking. Local bank accounts typically require strong substance evidence.

Personal banking for residents is straightforward; corporate banking depends on activity and structure. Bordercase coordinates introductions for non-standard cases.

Family reunification is supported on most routes. Schools (public, private, English, German, French) are widely available in Buenos Aires.

Family inclusion is supported. International schools are available in major regions.

Family relocation is supported on the work and start-up visa routes; schooling and healthcare access follow the main applicant's residency.

Family reunification is supported on most residency routes after a qualifying period. Schools (public, private, international) are widely available; the public system is generally accessible to legal residents.
