Thank you for your insights. which tends to shut off a line of inquiry which is relevant to the individual's eligibility, and which might well have resulted in a proper determination that they be inadmissible." So on known facts, my wife couldn't be qualified as non immigrant. I know someone can show the strong ties to their home country in many different ways(well paying job, owning a home, spouse and many more).I know all this will depend on the consular officer and his/her discretion. But I would like to understand your view on the following part:
but before the misrepresentation was discovered, the visa was refused because the applicant could not, on the known facts, qualify as a nonimmigrant. The subsequent discovery that the applicant misrepresented their well-paying job and is in truth unemployed would not support a finding of materiality because it had no bearing on the proper adjudication of the case.
c. (U) “Rule of Probability” Defined:
(1) (U) In General: The second part of the Attorney General's definition refers to a "misrepresentation which tends to shut off a line of inquiry which is relevant to the individual's eligibility, and which might well have resulted in a proper determination that they be inadmissible." These are cases where the exercise of further consular judgment is required. Past judicial and administrative decisions concerning this part have evolved into what has become to be known as the "rule of probability."
(2) (U) “Tends” Defined: The word "tends" as used in "tended to cut off a line of inquiry" means that the misrepresentation must be of such a nature as to be reasonably expected to foreclose certain information from your knowledge. It does not mean that the misrepresentation must have been successful in foreclosing further investigation by you to be deemed material; it means only that the misrepresentation must reasonably have had the capacity of foreclosing further investigation.
(a) (U) If an applicant was found ineligible for a visa under a different and unrelated ground of ineligibility (for example under INA 214(b)) a subsequent discovery that they had misrepresented certain aspects of the case would not be considered material since the misrepresented facts did not tend to lead you into making an erroneous conclusion. Let us use the example of an applicant for an NIV who made a misrepresentation on the visa application by claiming to have a well-paying job to show that the applicant has a residence abroad, but before the misrepresentation was discovered, the visa was refused because the applicant could not, on the known facts, qualify as a nonimmigrant. The subsequent discovery that the applicant misrepresented their well-paying job and is in truth unemployed would not support a finding of materiality because it had no bearing on the proper adjudication of the case.
