Heloo Shaurya,

I understand your concern and I am here to help you regarding your query and i acknowledge your interest towards Computer science after BCA.

So, yes you can pursue masters in science even after successful completion of Bca in India. In USA, you'll also have many chances to get plac d there itself. If you want settlement in India, then you can very well go for that also. And coming ro packages, it all depends on your performance during interviews and drives. Generally, it will bot go below 5 lakh per annum after master's in science.
