A visa is “an endorsement on a passport indicating that the holder is allowed to enter, leave, or stay for a specified period of time in a country”.
For citizens of the United States planning to stay in the United Kingdom for 90 days or less, a visa is not reguired; if you hold a United States passport, you do not need a visa for this program.
IMPORTANT NOTE: If you are not a citizen of the United States, you may be required to obtain a visa prior to travel. CISabroad is not a visa processing center. It is your responsibility to understand the immigration laws surrounding your country’s requirements for visiting the UK. Your program manager can provide documents you may need to support your visa application.
