USA Eligibility

I am not 100% sure but foreign universities doesn't consider BCA as an engineering course. I believe only B.Tech students can only pursue their MS in Computers from the US. BCA holds less value in the US. Although, you should consider talking with that university to clear the doubts.

Almost every university does and has one or the other schemes. Scholarships are typically based on merit. If you have an average profile look for universities in top 20 to 50 or 60 to make admission possibilities easier for you. Go through their websites and understand their requirements, aids etc. Applying early and during the first rounds of admission is the key to a successful application.

Hi Prabhat,
US universities are very flexible, take your GRE and have a good score to be considered eligible. Since you will be applying for a second Masters you must also show your interest in the programme through an excellent SOP. Relevant projects, recommendation letters etc. Must also be submitted. In general you must show that you are a good candidate for the programme and how you can contribute to the cohort or class.

This is good though of higher education but I think if you have good base in mechanical you should pursue Bachelor in mechanical engineering because Very large PSUs offer job in mechanical.

No, it is very less.

Hello,For abroad studies, most of the countries do not accept the education gap of more than 5 years. So, it will be difficult for you to go abroad studies. But, still you can consult it with a good study abroad consultancy.

It depends on college. Some colleges offer direct admission and in some colleges, you have to give entrance exam.

Yes, you can certainly do Diploma or 1 year Masters programme to apply for USA universities. But, the Diploma course should be done from a recognized university.
