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.

OOD (LLC) and EOOD (single-shareholder LLC) are common structures. Formation is well-documented. Corporate tax is at a flat rate; VAT registration depends on activity.

Maltese companies are commonly used for trading, IP holding, and gaming / fintech structures. Substance, accounting, and tax-refund mechanisms are well established but require careful structuring.

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.

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.

Personal and corporate banking for residents is broadly accessible. Source-of-funds documentation matters for non-standard cases. Bordercase coordinates banking introductions.

Local banking has tightened; EMIs are common supplements. Bordercase coordinates banking introductions through partners with current relationships.

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.

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 reunification is supported. Schools (public, private, English, German, French) are concentrated in Sofia, Plovdiv, and Varna.

Family reunification is supported on most routes. Schooling and healthcare are accessible to legal residents.

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

Risks Bordercase watches for in Mexico:

• Centre-of-economic-interests test for tax residency
• Real-estate restrictions in the "restricted zone" (50 km from coast, 100 km from borders) - fideicomiso or Mexican company structure needed

• Late-stage RFC and CURP registrations

Risks Bordercase watches for in Bulgaria:

• Tax residency triggers
• VAT classification on cross-border services
• Processing variations between regions
