People who tend to opt CPA (US or AUS), do so to be recognized with their qualifications easily in their jurisdictions. That allows immigrants to seek jobs in particular.
Atleast this is what I have seen.
However, CFA is an altogether another beast if you want to embark upon a career in Investment side or Financial Advisory services. It is worth the challenge, but a blind nosedive may not be fruitful. Gain some experience in this field on the basis of your MBA. Get an insight, then you will be in a better position to decide.
Decide your goals first.
Why do you want to go for MS finance btw? You already did masters.
