There are many courses which you can pursue with CA or CS. However the choice and decision depends upon many factors like one’s own interest, cost, duration, time devotion etc. depending upon your circumstances. In this regard I’d suggest you to explore your own interest and then decide what you want to do in future.
Some of the options available are:
1. CS, ICWA, CFA (US), CMA(UK). These are Long term duration with more than 3 years.
2. CPA, CFP, CIA, CISA etc. are medium term duration depending upon the devotion and your level of knowledge.
3. Further there are many certification programmes like, CIFRS, NCFM, CMA (US) etc. NCFM course is conducted by the Indian Stock Exchanges and concerned with security market.
The combination of CA+CFA is good in case the interest is for Investment banking and Portfolio Management.
The combination of CA+CPA is also a good one in case interest is in Accounting and Auditing field.
The Combination of CA+CS is also good. With this combination you will be able to handle Secretarial deptt along with Account and finance deptt. It is also very helpful to take top chances to work with top management.
