When we look at potentially 14,000 fraudulent letters of acceptance, we take the data and look at the indicators in each of those applications. Is there something that's consistent in each of those applications that identifies for us that this is a large-scale fraud or that individuals are trying to circumvent the program? We will issue reports or other types of packages for our officers, so that they can look out for those things in future applications. We've done that in other cohorts as well.
Last year, we were able to determine that there was fraud happening in the visitor program. We did the activities that I just mentioned. We were able to increase the identification of fraud and misrepresentation in that court by 241% over the course of a couple of months. That's the system that we look at. We get information from our partners, get tips, look at our own trends and look at those indicators to see how can that improve our processing and our ability to identify that fraud and abuse in the future.
