Nonimmigrant Admissions to the United States: 2007
"Nonimmigrants are foreign nationals granted temporary entry into the United States. The major purposes for which nonimmigrant admission may be authorized include temporary visits for business or pleasure, academic or vocational study, temporary employment, and to act as a representative of a foreign government or international organization. The Department of Homeland Security (DHS) collects information on the characteristics of certain nonimmigrant admissions, those recorded on the I-94 Arrival/Departure Record. This Office of Immigration Statistics Annual Flow Report presents information gathered from the I-94 on the number and characteristics of nonimmigrant admissions to the United States in 2007."
