Is my three-year BBA degree eligible for management courses abroad, or is a four-year degree required for a Master's?

Yes, your three-year Bachelor of Business Administration (BBA) degree from India is generally accepted for management master's programs abroad. Most international universities recognize three-year degrees from recognized Indian institutions.

However, some universities - especially in North America - may prefer or require a four-year undergraduate degree. Always check the specific admission requirements of each university and program.
