Of course, if the CBI passport is from St Kitts & Nevis, or Dominica, among certain other East Caribbean states, it may conveniently show that the holder actually was born in that nation, as the CBI units in those states tend to play fast & loose with the truth, especially if a certain amount of money changes hands, unofficially of course
Compliance officers, do not fret; there is a time-tested method of determining, painlessly, that your passport holder was NOT born there. Listen to him. Each country's native-born citizens speak their official language fluently, and with the accents and slang (or even patois) specific to their place of origin. If you do not have expats from the Caribbean on your New Accounts staff, hire some, for they and they alone will tell you, in a New York second, if your client is a native speaker.
Encourage your New Accounts staff to draw out the prospective client into conversation, for it is them that they will be able to alert you to his lack of accent, hestiation wihen discussing his hometown or place of birth, and relatives who supposedly still live there, and rely upon their conclusions.
If you are unable or unwilling to follow this advice, then the only alternative is to immediately classify all nationals from these CBI jurisdictions as potentially high-risk, and apply Enhanced Due Diligence before accepting their deposits. The jurisdictions that you will most likely encounter are:
St Kitts & Nevis
Antigua & Barbuda
