We received an extensive Request for Further Evidence (RFE) to support a Multi-national Executive and Manager petition on behalf of a Korean national who was a Maintenance Manager for a major airline. The petitioner did not have all documentation requested by the immigration service in the RFE. However, we were able to provide alternative documentation showing that the corporate petitioner still met the detailed statutory requirement, and that the Maintenance Manager had the required level of responsibility. As a result, the Immigrant Visa Petition was approved.
