However, IFRET’s previous research (Qualitative Research on Marriage-Based Immigration Benefit Fraud Detection) identified a number of strategies employed by ISOs to stop fraudulent cases from continuing through the adjudication process including denying petitions for other reasons (in which case, the “fraud” is not captured in USCIS data systems) and issuing a Notice of Intent to Deny (NOID). Each of these strategies demonstrate different thresholds for the concept of “fraud” with case denial for a reason other than fraud being the lowest threshold and the Agency definition of a fraud finding the highest threshold. IFRET has been tasked to estimate the “true” fraud rate, meaning IFRET constructed a research design that would capture these lower thresholds for fraud. In this way, IFRET believes the study will be able to calculate a confidence interval for the “true” fraud rate by capturing all instances of fraud irrespective of a formal Agency finding. IFRET agreed, however, to compromise and use the mid-level measure of fraud: the issuance of a NOID. It should be noted that this definition will generate a fraud rate that may be unrealistically low as not all fraudulent cases can be denied for fraud due to the stringent criteria set up by the immigration law and
