Once review is complete, ISO will email you a PDF of the approved visa request.The approved visa request must be routed for signatures and sent back to ISO. US work visas, like the H1B and L1, need sponsorship from a US employer. Here's how the process works, and how much it costs. File both forms at the location specified for the other application or petition. For example, if you are filing Form I-765 with Form I-539 or Form I-485. When asking for visa sponsorship in a cover letter, be direct and professional. A job offer is required and the U.S. employer must file an Immigrant Petition for Alien Worker, Form I-140, on behalf of the applicant.
