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.

Private Limited (Pte Ltd) is the standard structure. ACRA registration, a local resident director, and a registered office are required. Substance, accounting, and corporate governance standards are real.

SA de CV (Sociedad Anónima) and S de RL de CV are the standard private entity types. Formation involves a notary, RFC (tax registration), and IMSS where staff are involved. Mexican tax residency is triggered by primary home and centre of economic interests.

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

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.

Corporate banking has strong KYC and source-of-funds processes; relationship banking is common. Personal banking depends on residency status. Bordercase coordinates introductions through partners.

Resident personal banking is broadly accessible; corporate banking depends on activity and structure. Source of funds and ownership clarity are central. Bordercase coordinates introductions for cross-border cases.

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 relocation is well-supported via Dependant's Pass and LTVP routes. Schools (local, private, and international) are widely available; international schools are competitive.

Family reunification is supported on most residency routes. International schools (English, German, French, Japanese) are widely available in major cities; bilingual public and private schools are common.

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