I need to know what is future growth and opportunities for a CA if I join some Shared Services (US Audits). Currently having an offer for such a position, if I will join, will also pursue CPA(US). So, I need to know what can be the future growth, and also if I wish can I switch back to Big4 in Statutory or Internal Audit later on. Please guide me on this. Thank you in advance.
