Hello Japneet

I hope you are doing good . As per your query , I would like to inform you that you need to have 4 years of bacehlors to qualify the eligibilty in admission in masters in u.s  . Persuing diploma with bachelors doesnt qualify you for 16 years ,you need to have bachelors of 4 degree. Top universities of usa will not  consider your diploma in the count of 16 years of education

If you have any other doubt then you can always reach us to clear them :)

we are always available to help you out and guide you

Thankyou
