The L-1A Visa is intended for individuals coming to the United States to set up a new branch, affiliate, or subsidiary of an existing company. For this type of visa, the petitioner must provide evidence of the physical premises of the U.S. operation and demonstrate its capability to support an executive or managerial role within one year of the petition's approval. Additionally, financial information about the company is necessary. Initially, the visa may be granted for up to one year, but it can be extended subsequently.
