A U.S. visa is a document generally placed in a traveler’s passport that allows a foreign citizen to seek entry into the United States. The specific visa type is determined by the purpose of travel and other relevant factors under immigration law.

U.S. visa categories are broadly divided into two main groups:

  • Immigrant visas (for permanent residence)
  • Nonimmigrant visas (for temporary stays)

A consular officer at a U.S. embassy or consulate typically determines eligibility based on applicable laws.

Immigrant visas and their purpose

These visas generally lead to lawful permanent resident status.

Common purposes of immigrant visas:

  • Special immigrant categories
  • Diversity visa programs

Examples of immigrant visa categories:
