We use World Check and as I'm familiar with the product, it is a sanctions screening provider. It may help identify NRA's, but it is not intended to function in that manner.
We identify NRA's at account opening by inquiring if a potential customer is a U.S. citizen. If they are not we ask follow up questions to determine any jurisdictions that they have obtained citizenship and if they meet the substantial presence test or not.
