First things first! You will need a passport that doesn’t expire too soon -- at a minimum it should last for 6 months after your anticipated return from your study abroad program. Apply or renew now if you need to!
Important: Make sure you sign your passport before travel, as it's not a valid document without your signature!
Visas and Permits to Stay
Summer or Semester Study ONLY
For U.S. citizens studying in the United Kingdom for a summer or a semester term with no internship, a visa isn't required, but it's essential to bring along some key documents to present to border control upon arrival in the UK. You'll need to have a valid passport, proof of enrollment at a recognized UK institution, evidence of sufficient funds for your stay, and a return ticket or evidence of onward travel.
Semester Study + Intern or Yearlong Study ONLY
For students studying on the Study + Intern program at the University of Westminster or studying abroad in the UK for an academic year, a student visa is required. The application process is online, but applicants must go to a biometrics facility for fingerprinting and a photo. Avoid international travel before the study abroad program begins, as mailing your passport for the visa application is required.
