I guess I got your first post wrong. Are you saying that you are doing a Bachelor's degree and not JD ? In that case you would have to apply for a LLB course in India and that would be 3 years in duration and the universities and process is same. However, it is not a common entrance test and each university has its own test. However, an Indian LLB would not allow you to practice in the US, except for California and New York (where you might have to take a few additional courses). It might be better to complete a JD in US and then seek to do an LLM here, otherwise most of the US jurisdictions would be out of bounds for you.

you should opt for punjab university it has good reputation in studies

Delhi University has the best MCL (Masters in Comparitive Laws) program in the country. It is highly recommended that if u r planning to study MCL then you might wanna consider Delhi University seriously..

From my experience, as far as non-government employers are concerned correspondence courses in law in India are not worth the paper the degrees are printed on. However, if such a course is unavoidable, it is best to pursue such from NLSIU.
