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.

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

Exempted Companies, LLCs, and partnerships are widely used in fund and holding structures. Economic substance rules apply to relevant activities.

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.

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

Banking is mature but selective. Source-of-funds documentation is central. Bordercase coordinates introductions through current partners.

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 routes. Schools (public, private, English, German, French) are widely available in Buenos Aires.

Family inclusion is supported on most residency routes. International schools are concentrated on Grand Cayman.
