“Dear Colleagues,

“Since the weekend, we have been reviewing the executive order on immigration, as well as statements by administration officials, to assess its impact. As a U.S. company and the world’s most global financial institution, we are concerned about the message the executive order sends, as well as the impact immigration policies could have on our ability to serve our clients and contribute to growth. We have been advising colleagues who could be affected and will continue to support them and their families.
