Dear Chamkur, Different countries have different criteria for becoming CA. But there is an agency ACCA which has generalised the course for CAs across the world. ACCA certification is equal in all countries. The eligibility criteria is that you should be a Graduate in a 2 year Chartered Accountant Programme overseas after receiving a Bachelor's degree. Some of the best colleges to pursue CA in the world are : American Institute of Certified Public Accountants, Institute of Chartered Accountants in England and Wales, Canadian Institute of Chartered Accountants, Institute of Chartered Accountants of Scotland, Institute of Chartered Accountants of Ireland, Institute of Chartered Accountants of Australia, Edith Cowan University, Bangor University and London University. To be considered an ACCA accountant, you need to clear exams,  practical experience and an online ethics module. You have to pass a total of 14 papers to be eligible for thos certification. And you need to have a total of 3 years of experience before you qualify.
So ideally you can pursue the CA from the above said Institutions of the country of your choice and then put on 3 years of experience and qualify for ACCA certification. Once you clear the ACCA certification, you can practise globally.
