Today’s business world marches to the beat of change. Against the ever-shifting backdrop of global commerce, two companies across an ocean meet; their interests align; they agree to mingle assets.

Whether employees have a work visa of finite duration or a work authorization tied to a full employment-based immigration process, the impact of mergers, acquisitions and outsourcing cannot be overstated.
