CIMA Scope

CMA vs CIMA: An Overview
The CMA qualification is granted by the Institute of Management Accountants and is also known as IMA. CIMA stands for Chartered Institute of Management Accountants, is a designation which comes from the UK.
Membership and Network
Both qualifications were conventional since a long time, but CIMA has a much superior presence with 218K members and students. IMA has around 70,000 members.
Global Presence
In terms of global presence, CIMA conventionally has a more global presence and is well familiar in most places less so in the US but more so in the UK and Commonwealth countries. In current years, the CMA (now CPA) Canada and CMA Australia are getting more widespread in their respective countries so CIMA is disputably less sought after in these countries.
On the other hand, IMA has been vigorously building up its universal presence, remarkably in developing countries e.g. China and the Middle East. For now, CMA is well established in China and is head-to-head with CIMA in the Middle East.
At the same time, CIMA pairs up with AICPA to establish a new qualification known as CGMA. CIMA members can pretty much pay to get the new designation before 2015.
Conclusion
There isn't a superior or simpler qualification. As fellow reader Gunner pointed out in the comment section, while CMA may look easier with only two parts in the exam, it needs a Bachelor degree, vs a high school diploma in CIMA. Or looking at it the other way, as CIMA has a lower entry barrier, it has a more comprehensive exam with extra papers and time/effort in the preparation.
A more important consideration is where you would like to work in a longer term. This will help you select the qualification best suited in that region.

ACCA is indeed a good certification globally. But, in Indian context, it is still struggling to be relevant primarily because of already established professional certifications like CA and CMA. ACCA provides good exposure in globally relevant areas like IFRS and US GAAP. But again, in India ACCA doesn't have strong base compared to its local counter parts. A local degree course such as MBA along with ACCA can be a good combination in India.
This is my personal opinion. You may research further or take an advice from a qualified ACCA regarding the scenario in India.
CIMA certification will give you a overall knowledge of accounting as this is course is focused on management term you'll be able to answer the whys and whats of the accounts and actually provide a way forward. Management accounting is basically accounting for internal affairs, making decisions related to product, cost, time which affects business outcome. CIMA certification enhances your professional stature and opens up the opportunity to work with imminent clients and depicts that you are committed to increase your knowledge by studying further.
Pursuing CIMA doesn't put you at risk of losing your money for a long time. MBA does. The fees is affordable, the course is comprehensive (without fluff) and the subjects covered in the course are relevant.

Who told you they dont have scope at abroad?
CA ICWA CS are accepted all over world

Yes CFA have scope all over world and have good scope all over except like gem all over
These days some countries started accepting CIMA ACCA. In India CFA and CIMA are accepted
As CIMA Course is Equivalent to ICWA And in India CIMA do not have any recognition in Public sectors
so In my suggestion if you looking for these International Courses you must join it with any of Indian CA CS ICWA it will give you a great career prospects all over world.
Hope this will help
