Mbsr - sr 402

I would like to attend the mbsr SR 402 course. I recently relocated to the Bay Area from India. I have been practicing yoga and meditations for the past 6 years. I am very keen to learn MBSR and get involved in research in this field. I wanted to know if I did a foundation course in MBSR in the Bay Area with a qualified MBSR instructor would that qualify for the pre requisites for the SR 402 course.

I have a choice to study the 8 week foundation either with Dr. Julie Forbes at the Palo Alto medical foundation or with Dr. James Mitchell at the Osher center at UCSF.

I would really appreciate your advice as this is a new field for me and I would like to make sure I take the right course so that I can attend the course at the oasis center at Umass.
