Which CBI is best for a family of four?
Antigua wins on per-head economics for a family of four under the harmonised Caribbean five — its base + per-additional-dependant fee structure delivers the lowest total cost for spouse + two children. It also uniquely permits sibling inclusion among the operative programmes. St. Kitts and Dominica deliver comparable family economics with marginal differences in processing speed and banking acceptance.
For a family of four (principal + spouse + two dependent children), Antigua & Barbuda's CBI delivers the lowest per-head total cost among the harmonised Caribbean five. Antigua's family inclusion fee structure — base donation of $230K covering up to four family members — is the most family-friendly in the operative CBI estate. Critically, Antigua uniquely permits sibling inclusion among the harmonised five, which extends the per-application coverage. Dominica and St. Kitts deliver comparable per-head economics for a four-person unit but require additional per-dependant fees beyond the base. Outside the Caribbean: Malta CBI works for higher-budget families (€600K + per-dependant fees) wanting EU citizenship; Portugal Golden Visa converts to citizenship at year 5 with broad family inclusion (spouse + dependent children + parents over 65). For pure mobility-passport family economics, Antigua is the practitioner's recommendation. For EU citizenship pathway with family, Portugal is the consensus pick. The 5-day-in-5-years residency requirement under Antigua is the only operational catch — manageable for almost all family profiles.
