The due-diligence fee covers a thorough background check of the prospective applicant by the Financial Intelligence Unit (the authority responsible for the fight against money laundering and terrorist financing). Vanuatu does not want to grant citizenship to applicants with a criminal background or questionable past, so the personal details, amongst others, are checked in international databases, such as World-Check, international sanctions lists such as issued by OFAC, at Interpol and in social media, such as Facebook, Google and LinkedIn. The only tip I can give you that if you have a red flag in your past, you need to consult your professional advisor or possibly you should choose to apply to another country.
