As of my last update, there hasn't been an official announcement regarding the full cast of NCIS: Los Angeles returning for the next season. While many main cast members typically remain, changes can occur due to contract negotiations or new story directions. It's best to check official sources or news updates for the most current information about the cast for the upcoming season.

NCIS Los Angeles too premiered on the same date that its original series NCIS premiered. They both premiered on September 20th 2011 - back to back. This season we will get to know the past of the head of NCIS LA and how the team handles it. So its gonna be very interesting.
It has been confirmed that Ziva will be back for season 7. There is no reason why McGee wouldn't be back
Yes.
Yes. It has been confirmed that she will be back in season 7
Tim McGee
yes she left the team. But I think that she will be recused by the NCIS team because of the way the last season ended. The reason i think this is because she was being tortured by someone. One your family you are always family. Family rescuses each other when they are in trouble. It has been confirmed that Ziva will be back for season 7
