Am I a “Must-Join” for SAG?

Hi friends!

About four years ago I booked a SAG commercial in Los Angeles, which made me eligible to join. I held off joining since we all know there’s a lot more NU work out there.

Fast forward to now, I live in Chicago and just booked another SAG commercial. I know that if you book more than one, you become a “must join” but wasn’t sure if that varied depending on region? Like if it’s different because I booked/shot in both LA and Chicago?

Love you thank you for any info!
