Getting a U.S. Visa

Getting a U.S. Visa

Visa requirements vary based on national origin, current residence, previous travel and passport eligibility. It is your responsibility to secure any required visas, and travel documents.

  • The¬†U.S. Department of State¬†is the most trusted source for up-to-date information on¬†visa¬†questions.
  • The Visa Waiver Program¬†(VWP) enables most citizens or nationals of participating countries to travel to the United States for tourism or business for stays of 90 days or less without first obtaining a visa, when they meet certain requirements.
  • The¬†Visa Wizard¬†is a tool to help travelers understand what type of visa they may need.

When should I apply?

We recommend that you complete your application for a visa as soon as possible. The approval process can take several weeks and may require an interview. Contact the U.S. Embassy or consulate in your country for specific application procedures and estimated wait times for interview appointments.
