Fallon, Bixby, Cheng & Lee is the oldest practicing immigration law firm in San Francisco. It was founded by Joseph P. Fallon, Sr. in 1925. In the 1940s, Mr. Fallon invited his son Joseph Fallon Jr. to join and later take over the firm. Mr. Fallon Jr. remained a partner until 1983. Mr. Fallon Jr. had met Mr. Robert Bixby when they both served in the U.S. military during World War II. He invited Mr. Bixby to join the firm in the 1980s. Ms. Angeli Cheng started working for the firm in 1971 as a paralegal; after taking time off to attend law school, Ms. Cheng returned to the firm in 1980 as an attorney and became a partner in 1985. In May 2000, Ms. Cheng sold the firm to Ms. Lucy Fong Lee who continues to run the practice today.
