Students are required to have a Tier 4 Visa for Medical Electives. The process is that: King’s College will issue the student a “Confirmation of Acceptance of Study” letter and number (CAS number) but, the student must apply for and obtain the Tier 4 Visa before arrival in the UK. Students without a Tier 4 Visa will not be able to take the elective. This applies to students undertaking clinical placements within one of our four trust hospitals. Students undertaking a research placement can apply for a Student Visitor Visa and will not be classed as "working placements" by the UK. If a student does not have a Student Visitor Visa, he/she will not be enrolled at King's. Students need to provide evidence that they have malpractice insurance. If not, then students will be placed in a hands-off/observership placement.
