ICWA or CA...Opinion


I want to do ICWA but so many people told me that ICWA has less scope than CA and he also tells me both are equally tougher ? As I am working in BPO and I do not able to give full time to any of them...... Please give me your opinion?

Why CA has better prospectus than ICWA inspite of easyness? I saw so many persons doing CA/CWA and most of them are facing difficulty in passing ICWA than CA.?
