Once a family grows beyond four people, a dangerous phrase often appears on the quote: one more dependant. Under Saint Kitts SISC, the official structure does not treat all extra family members as the same. The age-18 split, the age-16 due-diligence layer, and the interview requirement all reshape cash flow and timing. Once different ages are merged into one vague dependant category, the budget table and the preparation table both become too thin.
Read the official checklist first. As of June 6, 2026, As of June 6, 2026, the official Saint Kitts and Nevis CIU page for the Sustainable Island State Contribution says the minimum contribution is US$250,000 for a main applicant or a family of up to four members. It then sets additional dependants under 18 at US$25,000 each and additional dependants aged 18 or over at US$50,000 each. The same page states due-diligence fees of US$10,000 for the main applicant and US$7,500 for each dependant aged 16 or over, while also saying the main applicant must attend an interview and dependants aged 16 or over may also be required to attend if deemed necessary. Rules like these may look dry, but they are often the exact points that make a family file either workable or unstable.
Direct answer: what to check first for Saint Kitts SISC dependant age split
Saint Kitts SISC dependant age split should be judged by the constraint it changes rather than by the headline. SISC is useful because the route is direct and a main applicant or a family of up to four can enter through the same contribution line. The limit is clear: But once the file exceeds four people, age rewrites the add-on rule first and prevents all dependants from being treated as an average. A Passport-First file lines up the applicant, dependants, payer, document set, and follow-up questions before money moves. A second passport can widen mobility and family options, but it does not remove due diligence, KYC review, tax boundaries, or later admin. I only treat a route as ready when a spouse, banker, or adult child can ask one basic question about timing, cost, or responsibility and still receive the same factual answer. The structure should also survive one ordinary change without forcing the whole story to be rewritten.
Separate the fifth and sixth members before pricing them
The usual misread is to price the fifth or sixth family member as though each extra person costs the same. The official page does not work that way. It first asks whether the file has moved beyond four members, then whether that person is already 18, and then whether the 16-plus diligence and interview layer also needs to be budgeted.
I have seen many families write a 17-year-old and a 19-year-old simply as two extra dependants. The issue is more than the wrong number. The family also underestimates how the 16-plus diligence and interview logic can change preparation and timing at the same time. In family work, the phrase I trust least is “they are all just dependants.” Once the official age line appears, preparation has already stopped being uniform.
Who should build the age table before asking for the total
This deserves the first look from larger families, households with older teenagers, or anyone deciding whether a fifth or sixth person belongs in the same file. Their Saint Kitts challenge is not the US$250,000 base line but the layers that come after it.
A second passport can add another planning layer for the household, but it does not smooth away age, diligence, or interview requirements. Prepare the full family age table, define who will be in the same filing, map the due-diligence position for every person aged 16 or over, write out both age-based add-on contribution lines, and decide how the budget changes if someone joins later.
A four-step family budget checklist before filing
Check first whether the file is above four members. Then confirm whether each additional dependant is 17 or 18, followed by the 16-plus due-diligence layer, the main-applicant interview, any dependant interview risk, and only then the total budget.
Larger families are hurt less by spending more than by grouping people too loosely at the start. By the time the formal forms are opened, each age point can already carry a different consequence.
Ken's working order
My order is to turn the family count into an age table before I judge Saint Kitts SISC. If the quote still says only “one more person,” the calculation has barely started.
FAQ
Does the dependant age split affect only cost and not timing?
No. Age lines often change due diligence, interview exposure, follow-up documents, and budget at the same time, so they are timing issues as well as cost issues.
Can the family take one total price first and split the relatives later?
That is usually a mistake. Once the ages and roles are broken out late, the quote, the diligence plan, and the filing rhythm all have to be recalculated together.
What should be prepared before speaking with an adviser?
List each family member’s age, relationship, filing status, and whether the person has crossed 16 or 18. Many pricing questions become obvious once that sheet exists.
If you are reviewing a Saint Kitts and Nevis family file, write the age table before you judge the total cost. Start with the case reviews, the decision map, and USA60. Official reference: Saint Kitts official SISC page.
A file becomes easier to judge when the ordinary facts are written down early. Who pays, who signs, who answers questions, and what happens if one family fact changes are basic points, but they carry most of the execution risk.
I prefer a plain working memo to a polished story. The memo usually exposes the weak point before money moves, which is still the cheapest moment to discover it.
Applicants should separate legal availability from practical fit. A route can exist in the rules and still fit the household badly once timing, banking, and document pressure are added.
The stronger file usually sounds less exciting. It reads like something a spouse, banker, or adult child can repeat later without changing the facts halfway through.
That standard keeps the planning honest. If the route depends on urgency, prestige language, or a vague promise that details will be handled later, the structure is still too soft.
