Each club in Major League Soccer is allocated 8 international roster spots, which can be traded.

There have been no reported trades involving Chicago international roster spots for the 2011 season.

For clubs based in the United States, a domestic player is either a U.S. citizen, a permanent resident (green card holder) or the holder of other special status (e.g., refugee or asylum status).

It is believed Chicago maintains the MLS rights to Carlos Bocanegra, Wilman Conde, Freddie Ljungberg, and Chris Rolfe as each of these players declined contract offers by the club and signed overseas on free transfers.
