Jeong will play the Examiner - the role played by Robert Lindsay in the UK original, Deadline reports.
Rob Corddry will star in ABC's Spy as Tim, a father of a young son (Mason Cook), who inadvertently finds himself recruited as a secret agent.
Criminal Minds star Paget Brewster will also feature in the pilot as Tim's cold, neurotic ex-wife.
Jeong stars on NBC comedy Community. His Spy role is in 'second position' to his current commitments, meaning that he will have to forfeit the part if Community is picked up for a fifth season.
The fourth season of Community opened strong with 3.88m viewers, but the show's most recent episode hit a series low of 1.1m in the 18-49 demographic.
Jeong will also be seen reprising his role of Mr. Chow in The Hangover Part III later this year.
