While GPs can choose whether or not to accept new patients, individuals seeking to register do not legally have to prove their identity or immigration status. Consequently, migrants should be able to register for primary care irrespective of their immigration status. With several partner organizations, the Mayor of London has published a leaflet explaining how excluded groups, and particularly migrants in an irregular situation, could access primary health care in London. Examples of such initiatives are the "Checking for Change" programme in Scotland, United Kingdom, and the "Migrant-Friendly Hospitals" network, which is sponsored by the Directorate-General for Health and Consumers of the European Commission.
