UCLA/UCB Extension F1身份问题

想请问地里的各位朋友，如果在UCLA/UCB读一个extension学位，在读期间可以有机会获得CPT 边读边实习？以及在读期间是否可以回国？
谢谢！

To obtain CPT, a student must:

Be in valid F-1 immigration status for at least two semesters (except graduate students who must work as a requirement for their degree).
Have completed at least one academic year as a full-time student in a SEVIS-approved college, university, conservatory, or seminary immediately prior to the CPT authorization. The only exception is for graduate students enrolled in a degree program that requires an internship of all students prior to the completion of one academic year.
Secure an academically appropriate internship offer directly related to the student's field of study. NOTE: Positions must be appropriate to the student's level of study and major field of study. Retail sales, food service, and other unskilled positions will be denied.
Obtain CPT authorization BEFORE beginning employment; authorization cannot be back-dated.
Be registered for classes at UC Berkeley; CPT cannot be used when a graduate student is on Filing Fee status.
Additionally, the student's supervisor for the internship can not be an F-1 or J-1 student.

学完一年后，部门专业可。
