Texas Service Center to Begin Processing Form I-129 for L Visas On February 12, 2018, the Texas Service Center (TSC) will begin processing certain Form I-129, Petition for a Nonimmigrant Worker petitions for L nonimmigrant classification, also known as L visas. The TSC will share this workload with the California Service Center to balance workloads and to provide flexibility as USCIS works towards improving processing times and efficiency. The Vermont Service Center will no longer process any new Form I‑129 petitions requesting L nonimmigrant classification. Petitioners requesting an L nonimmigrant classification should file their Form I-129 at the address indicated on the Direct Filing Addresses for Form I-129, Petition for a Nonimmigrant Worker page. Starting March 12, 2018, USCIS may reject any of these applications that are filed at the wrong service center.
