The primary transfer window closes at 10:00 PM PT on Tuesday, May 7. MLS teams must have paperwork filed with the league office by that time for any talent they wish to add that requires a transfer fee or a trade within the league. After this time, teams can still add “frees” who were out of contract before the cutoff, and they can sign talent from within the US soccer pyramid and HGPs. The next opportunity to add players who require a transfer or trade will be during the secondary transfer window, which will be open July 9 through August 7.
