Excerpt of 1941 letter from Ruby Whang:

Chin Back Pang, who was in his early 50s or 60s, was arrested in Portland, Oregon in May 1941—he was a Chinese-born laborer without papers. He arrived in the United States as a stowaway about 1918.
Ruby Whang, a 17-year old Korean girl from Gresham, Oregon sent a letter to E. P. Marsh at the U.S. Court House in Portland. The letter was forwarded to Marsh in Washington, D.C. He knew nothing about the case or how Whang got his name. He forwarded to Roy Norene at Immigration in Portland saying the letter “has a very appealing tone…”
There is no information in the file of how it was discovered the Chin was an illegal. He worked on a farm and there is no mention of him getting into trouble.
A letter from the Federal Bureau of Investigation “fails to disclose prior arrests or criminal data…” [The letter is signed with the signature stamp of J. E. Hoover.]

Chin Back Pang was deported.
