First, you would have to give IELTS and later you can apply to universities in New Zealand because they have free application submission, but if you want to spend a fortune on applying then go for US and Canada.

You will be able to get job easily after MS and work for maximum 29 month under industrial training visa program. In the meantime, you can apply for H1 visa to continue working in USA.

Hi
I would suggest you to get some work experience first as that will help you in two ways. Firstly, your profile becomes better as universities do look for it for MS. Secondly, you will be able to decide upon which specialization is best for you as per your skills, interest and core strengths.

ECE followed by IT.

Dear Akash, opportunities are immense in research organizations, defence sector and academic institutions. USA is home to the major organizations such as NASA, remember that India is not behind as well. Outstanding academic performance, high level of intellect and problem solving qualities must be demonstrated. Majority of the students pursue their Ph.D as it is required for a large number of jobs in this area. Look for internship in one of the major organizations and establish professional contacts.
Best Wishes
