Commonwealth Professional Fellowships support mid-career professionals from developing Commonwealth countries to spend a period of time with a UK host organisation working in their field for a programme of professional development. Fellowships are typically three months but can be between one and six months in length, and can include limited time for attendance at short courses or conferences, as well as visits to other organisations.  The fellowship covers the living expenses for the Fellow as well as a return airfare to the UK and the visa application fee.
