More than 2 in 10 interpreters and translators are self-employed. To find work, these interpreters and translators may submit resumes to 100 or more employment agencies, and then wait to be contacted when an agency matches their skills with a job. After establishing a few regular clients, interpreters and translators often hear of subsequent jobs by word of mouth; or, they may receive enough work from a few clients to stay busy. Many who freelance in the occupation work only part time, relying on other sources of income to supplement earnings from interpreting or translation.
