SRINIVAS,
it is better you pick up ICWA, because you will be going in one streem ie accounts, in cwa will be added advantage along with ca, for many accounts officer positions in govt/pvt organizations they are asking for CA/CWA. so after qualifing both when you join as asst manager accounts , then you can easily grow up streem with both qualification , because both will support your accounting knowledge.
But suppose if you do CS with CA, then if you join as asst manager accounts using your ca, then cs will no where help you, because cs work is completely different with ca.
suppose if you join basing on cs, as a company secretary, then in small organizations they will burden you with accouns works also, where you have to manage two differen works with less remuneration, and it will effect your peace of mind. in big organizations if you join as cs, there will be hirarcy where you will looking only cs work and you cant even touch ca work.
so long run, better options are ca+cwa
or cs+llb
cs+MBA (hr)
or CA+MBA(finance).
so now iths up to you.
