  • Publication number: 20220156348
    Abstract: A method for remotely verifying a non-resident alien's identity, includes: receiving a request to establish a communication session from a user device; analyzing the request to determine whether the user device is compromised; in response to determining that the user device is not compromised, providing a page flow to the user device to solicit information from the non-resident alien, the information including identity information associated with a local foreign government identification document (ID), and other information not shown on the local foreign government ID; querying one or more foreign governmental data stores to identify foreign data associated with the non-resident alien based on a unique identifier associated with the local foreign government ID; comparing the information with the foreign data; and verifying an identity of the non-resident alien based on the comparing, wherein the verifying includes determining that at least one of the other information matches the foreign data.
