On Monday, PwC and New York-based immigration law firm, Fragomen, announced a “strategic alliance”. In a joint statement, the firms said the alliance would see the two firms collaborate and jointly market their immigration services. It also stated that their new arrangement would give them the ability to come together to provide “integrated services” to their clients.

The deal is far more consequential than the dry press release suggests. The alliance will speed up the Big Four’s already quick, expansion into the immigration space. It will also serve as a test case for partnerships in other areas of the legal industry.
