As of May 2026, the headline-price gap between Saint Kitts citizenship by investment at $250K NDF and Antigua at $230K NDF is only $20,000. Add family fees, residency obligations, and five years of holding cost, and the real family-of-four gap stretches to $60,000-$90,000. This breakdown lays out the cash, government charges, residency burden, and hidden costs side by side so you can see where the headline price stops telling the truth.
Saint Kitts vs Antigua family of four cost ledger: five-year cash side by side

On paper Saint Kitts citizenship by investment costs $20,000 more, but Antigua carries the hard 5-day landing obligation. A family of four flying from mainland China round-trip to Antigua runs RMB 30,000-40,000 in tickets, plus 5-7 nights of food and lodging on island — about $20,000 per trip in real terms. If a parent is elderly or the principal's calendar is tight, those five days become "must-take vacation." Saint Kitts has no landing requirement at all — the passport can sit unused for five years with no consequence. Once that $20,000 trip cost lands in the ledger, the five-year totals essentially tie, and Saint Kitts may even come out marginally cheaper.
The real gap is not five-year cash. It is year-ten renewal and program stability.
Of the 300+ families I have walked through these two programs over eleven years of work from my home office in Los Angeles, roughly 40% chose Saint Kitts citizenship by investment and 25% chose Antigua. The split is not just five-year math — it is about year-ten renewal obligations and program institutional stability. Since April 2024, Saint Kitts has run two streams: Priority One expedited (60-day approval) and the Sustainable Island State Contribution (SISC). Both run cleanly through channels with direct working history with the past two heads of the Saint Kitts CIU. Antigua's IIU swapped directors in late 2025, processing times have stretched from 4-6 months to 6-9 months, and whether further fee hikes are coming is being told different ways by different agents.
The 5-day landing requirement is undervalued by many families. A Fujian client I worked with in 2024 took the Antigua family-of-four route. In year four of his five-year window, his elderly parent broke a hip. His own company project would not release him. He flew to Antigua in the last two months of the window to backfill the residency days, came back to Beijing, and caught pneumonia that put him in hospital for two weeks. Had he known earlier that Saint Kitts had no such obligation, he would almost certainly have paid the $20,000 headline premium to avoid the obligation entirely.
Beyond the five-year math: what else Saint Kitts citizenship by investment offers
Three pieces matter beyond cash. First, expedited processing. Saint Kitts Priority One closes in 60 days at $25,000 per principal extra, fitting families with hard deadlines — corporate acquisitions, frozen-account risk, school admission cutoffs. Antigua has no official expedite. "Fast-track" requests there are agent-pulled favors with unpredictable outcomes. Second, biometric rollout. Saint Kitts mandatory biometrics from April 2025 allow applicants over 65 to enroll at consular service points in China. Antigua's mandatory interview and biometric rollout, effective 2026, requires in-person attendance for all family members 16 and older. Third, visa-free access. Saint Kitts reaches 156 countries (Schengen 90/180, UK 180 days, Singapore, Hong Kong), Antigua 151. The numerical gap is small but Saint Kitts adds a few extra Asian hubs.
Antigua has advantages Saint Kitts cannot match either. First, the family-of-four headline runs $20,000 less. Second, the 5-country Caribbean residency pact effective 2025 lets Antigua passport holders enjoy 30-day visa-free residency inside Saint Kitts, Dominica, Grenada, and Saint Lucia. Third, IIU source-of-funds review is somewhat more flexible — not lax, but its tolerance for "harder-to-document" funds (private equity exits, family trust distributions) runs about 15-20% higher than Saint Kitts.
