Search by Docket Number

  • To search for a case by Docket Number, you must include the dash in the Docket Number (e.g., 123-18).
  • You may, but do not have to, include the letter suffix (S, L, SL, R, X, D, or P) of the Docket Number to find a case.
  • When you enter a Docket Number that matches a case in the system, that case will display. If you enter a Docket Number that has no matching case, you will get a “No Matches Found” message.


Search by Name

  • To search for a case by petitioner name, you must enter the petitionerʼs full or last name. Partial name searches (e.g., entering “Ron” for Ronald) are not currently supported.
  • You can improve your search results by adding year filed, country or state. For the state filter - you will see U.S. Territories and military bases are included. These fields are not required but can be used in any combination to refine results.
