Residency

Saint Kitts and Nevis routes:

  • Citizenship by Investment (CBI) via the Sustainable Growth Fund
  • CBI via approved real-estate investment
  • Standard work / family routes

Citizenship outcomes remain at the discretion of the Citizenship by Investment Unit.

Estonian residency routes:

  • Start-up visa - for founders of qualifying start-ups
  • Digital nomad visa - for eligible remote workers
  • Work permit - employer-sponsored
  • Family routes - spouse / dependants

Note: e-Residency is NOT a residence permit - it is a digital identity for managing an Estonian company remotely.

Serbian residency routes:

  • Temporary residence via employment
  • Self-employment / business
  • Real-estate ownership
  • Family reunification
  • IT-focused residency framework

Permanent residence typically after 3 years of continuous temporary residence.

Company setup

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.

DOO (limited liability) is the standard structure. Formation is well-documented, with online steps available. Tax registration (PIB) and APR (Business Registers Agency) registration follow.

Banking

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.

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

Family

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. International schools (English, French, Russian) are available in Belgrade.
