The part of the process clients worry about most — the background checks — is the part that makes their new passport worth having. Due diligence is not a hurdle a good advisor helps you dodge; it is the mechanism that keeps a programme reputable and its passport widely accepted. This guide explains what the checks involve and how an application actually proceeds, so there are no surprises.
What due diligence actually checks
Every programme we advise on screens each adult applicant across a few dimensions: source of funds (evidence the money was earned lawfully — salary, business profits, sale of assets, inheritance), criminal-record and police clearances, sanctions and watch-list screening, and reputational checks. Some programmes commission independent third-party investigators on top of the government's own review. You can find these terms defined in the glossary.
Why rigour is a good thing
It is tempting to see strict checks as friction. In reality they are the reason a passport holds its value. A programme that screens carefully keeps bad actors out, which keeps other countries willing to grant its citizens visa-free access. When due diligence weakens, visa-free agreements come under pressure — so the scrutiny you go through is directly protecting the asset you are buying.
The typical sequence
Most applications follow a recognisable path. Consultation and selection — we assess your profile and shortlist programmes. Document preparation — we assemble and prepare your dossier to the exact standard the authority requires. Submission — your file is lodged through the official or government-approved agent, and you receive a reference number. Government processing and due diligence — the authority runs its checks and may raise queries. Approval in principle — confirmation your application has passed. Investment and issuance — you complete the qualifying investment and the passport or residence permit is issued. Our process page sets this out step by step.
How long it takes — and what slows it down
Timelines range from around a month for the fastest citizenship routes to a year or more for some European residencies and far longer for US EB-5. The biggest avoidable delays come from incomplete or inconsistent documentation — a missing clearance, an unexplained gap in source of funds, mismatched names across documents. Getting the dossier right the first time is the single largest lever on speed, which is why preparation matters more than chasing.
How to give yourself the best chance
Be transparent and thorough from the start. Disclose everything to your advisor — surprises discovered by a government investigator are far more damaging than anything declared upfront. Keep your source-of-funds story clear and documented. And choose an advisor who runs a pre-submission due-diligence screen on your file before it ever reaches the government, so weaknesses are addressed in private rather than in an official refusal.
