Over 20% of CGCA members are located outside the United Kingdom, and there are active groups of Association members in Hong Kong, India, Australia, South Africa, Malaysia and the United States. These often operate in association with other Imperial College member groups. Members travelling abroad who will be spending time near any of the Overseas Branches are strongly encouraged to make contact in advance (this can be done through the CGCA Office), with a view to being able to meet Branch members. Where schedules permit, the Branch may be able to organise an informal gathering for exchange of news and information in a relaxed and sociable atmosphere.

​

There are also many other Imperial College alumni associations (not specifically affiliated to CGCA) in various countries. For details of these, please contact Zeba Salman by telephone on +44 (0) 20 7594 6131 or by email.
