To obtain a visa for the UK, one must determine what type of visa is required based on their citizenship, country of residence, and purpose of visit. Then, the online application must be completed with passport and travel details. An appointment must be scheduled at a visa application center to provide fingerprints, a photo, and submit documents. Finally, the visa will be granted or an interview may be requested, and the approved visa can later be picked up.

1. How to Get a Visa for the UK
American tourists staying in the United Kingdom for less than six months are not required to obtain a visa; however, U.S. citizens planning on working, completing volunteer
work or attending a year of school in the U.K. must apply for a visa prior to their visit. Visa applications take time to process --- file yours well in advance of your travel dates.
Step 1
Determine the type of visa you need by visiting the U.K. Border Agency's "Do I Need a Visa?" web page. Provide information about the purpose of your visit to the United
Kingdom, your citizenship and your country of residence to learn which type of visa, if any, is required for your trip.
Step 2
Complete the online visa application, available on the U.K. Border Agency website. Before beginning the application, make sure you have access to your passport, travel dates
and itinerary and the address of where you'll be staying while you're in the U.K. Save your application often, by clicking on the pause button when it is available. Once you have
completed the entire application, pay any required visa fees and print a copy of your application to submit at a visa application center.
Step 3
Schedule an appointment at the nearest visa application center by using the U.K. Border Agency's online scheduling tool, available once you have finished your visa application.
The appointment is required so that your biometric information, fingerprints and photograph can be obtained and your printed application and supporting documents can be
submitted.
Step 4
Visit the visa application center at your selected time. Bring along a printed copy of your visa application, your valid passport and any other documentation required for your
specific visa type. Make sure your fingertips and face are clean and free of cuts or markings before arriving at the center, and remove any sunglasses and nonreligious head
coverings before having your picture taken.
Step 5
Complete an interview with a U.K. visa officer if one is requested. While most visa applications are processed and returned without incident, occasionally an interview must be
scheduled to clarify any questions the officer has about your application.
Step 6
Pick up your visa and supporting documentation from the visa application center once you receive word that your visa has been granted.
