Answer
If you are registered in the 50-week program prior to January 1, 2018 you can still work up to 50 weeks as an EMC, or join any time after 25 weeks, as long as all EMC and non-Equity work is complete. You will use the new form to continue to report points any time you work at an EMC-eligible theater but you do not need to enroll in Phase II to work more than 25 weeks.
