Asian Pacific American Heritage Month celebrates and recognizes the accomplishments of Asians and Pacific Islanders in the United States.  May was chosen to commemorate the immigration of the first Japanese to the United States on May 7, 1843, and to mark the anniversary of the completion of the transcontinental railroad on May 10, 1869.  The majority of the workers who laid the tracks were Chinese immigrants.
