Corporate entities for international business (formerly IBC) are well established. Substance and reporting requirements apply.

Nevis IBCs and LLCs are commonly used in international structures. Substance, beneficial ownership disclosure, and AML standards have tightened 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.

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

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

Domestic and offshore banking options exist but have become more selective on KYC and source of funds. Bordercase coordinates banking pack preparation and partner 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.

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

Family inclusion is supported. International schools are limited but present.

CBI applications can include qualifying dependants - spouse, children, and in some cases parents - under specific conditions.

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.
