Almost half of the firms ranked in this year’s Am Law 100 have an office in Hong Kong, making the Chinese special administrative region the No. 1 destination for expansion in Asia by U.S. firms.

There are 46 law firms with Hong Kong offices in the Am Law 100, which ranks U.S. firms by gross revenue. That number includes new arrivals in the past year Locke Lord Bissell & Liddell; Gibson, Dunn & Crutcher; Wilson Sonsini Goodrich & Rosati; and Nixon Peabody. As an overseas location for Am Law 100 firms, Hong Kong is second only to London, which hosts 75 of them.
