Many visa options exist to enable U.S. manufacturing companies to employ talented professionals, researchers and managers who are not U.S. citizens or permanent residents. This article will introduce the primary nonimmigrant (temporary) visa categories used by U.S. manufacturing companies to employ foreign national workers. The article will also provide key information about the permanent residency (green card) process. Manufacturing employers typically employ foreign nationals initially in a temporary nonimmigrant visa category. Thereafter, the manufacturer may begin working on a permanent residency case once the company has determined that it wishes to try to employ the foreign national on a permanent basis.
