USA visas are either immigrant or nonimmigrant. If you intend to visit the country for a specific purpose and period of time, then you need a nonimmigrant visa. If on the contrary, you intend to permanently live and work in the U.S., you must apply for an immigrant visa. Keep in mind that these are only broad categories, there are numerous visa types and you must select the one that best fits your case.
