A more thorough explanation:

A foreign jury is a group of jurors selected from a different jurisdiction than where the case is being tried. A jury is a group of people chosen by law to decide questions of fact and return a verdict in a case.

For example, if a case is being tried in New York, but the jury is selected from New Jersey, it would be considered a foreign jury.

Foreign juries are not commonly used in the United States, but they may be used in international cases or cases involving multiple jurisdictions.

Overall, a foreign jury is a group of jurors selected from a different jurisdiction than where the case is being tried.
