Boosting its immigration practice, Dorsey & Whitney said Thursday that it has absorbed a three-lawyer boutique, the Webber Law Firm, based in a Minneapolis suburb.

The boutique’s principal attorney, Robert Webber, has joined as a partner and co-chair of Dorsey’s immigration practice group, along with senior attorneys Candelario Arredondo and Penni Frank. A team of six paralegals and an administrative specialist are also joining the Minneapolis-based Am Law 200 firm.
