Julia Onslow-Cole, regarded as the ‘expert’s expert’ by peers, continues her leadership on all aspects of immigration matters. Recent highlights include her appointment to the Board of Council for Global Immigration in Washington and her appointment to the Mayor of London Brexit Experts Advisory Group. She also gave expert evidence in the European Parliament, on the economic impact of restricting EU migration. The head of over 1,600 legal experts at PwC’s immigration offices in over 174 countries sees the geopolitical storm increase uncertainty for the firm’s global clients. But Onslow-Cole is proud of PwC’s positioning at the heart of private clients worldwide, describing its ‘unrivalled access to governments’ and ability to ‘rapidly respond to large scale, significant changes’ in real time.‘We are able to seamlessly support clients on a worldwide basis to holistically manage their affairs in a fast-changing environment,’ she says. The Brexit vote has had a ‘formative impact’ on business owners, who have started to adapt more strategic measures to achieve long-term goals. PwC helps entrepreneurs through the maze of uncertainty in a joined-up approach, collaborating across the firm’s broader spectrum of legal, tax, consulting, social security, and change transformation strategy experts. Onslow-Cole and her team advise on a wide range of matters, but particularly on ‘extremely complex’ UHNW cases.
