Firstly you need to get a Bachelors Qualification in Commerce or Economics, or perhaps if you are from Engineering Background you need to develop skills and certifications in Finance and Financial Engineering as well as Technical and Data Analytics Skills which are critical for the Technical Domains of all Banks. If you are in management, you need to complete you MBA with focus in Finance.

Following your degree you need to preferably acquire a work experience in India at a leading Bank in either Public or Private Sector like SBI, ICICI, HDFC, Axis or Financial Technology, Consultancy, Insurance Companies and Hedge Funds like Groww, BlackRock, Bank of America, JP Morgan, Morgan Stanley and so on.

Following atleast a 2 year experience and a couple of good projects you will have a good profile and should apply on Job Websites like Indeed, LinkedIn and so on, followed by Interview ans Shortlisting. As far as Australia and England are concerned getting a work visa is comparatively easier than United States.

However there is another way, you can perhaps go for a Masters in Finance or Management, in England or Australia after your Bachelors in India, that too is a good way of moving abroad.

I believe you should follow this way and if you have proper Qualifications and Talents, you might just make into a job.
