Diploma

It is up to them, as there is no rule for that.

1. You should apply for government jobs like BEL, Metro or BHEL.
2. If you want to further study, you should opt for Bachelors in technology.

Hello Karandeep
I suggest you to talk to Ms. Chetna on https://shiksha.com as she is best in study abroad program and she will help you in finding the best course for your brother.

You have right qualifications to start your careers as supervisor in any electrical or electronic firm or in any manufacturing / services unit as maintenance supervisor. Along with job, you are advised to do AMIE. If you plan to study further, you may seek lateral entry in B.Tech degree course. You may take decision based on your interests and personal conditions.

I suggest that you to pursue Masters in Kinesiology rather than a Post Graduate Diploma program. University of Calgary, University of British Columbia, University of Waterloo, and University of Waterloo are some of the universities that offer Masters in Kinesology.

Any educational degree from UK is accepted all over the world. You need to be sure of what you are going to do with it. Since you haven't mentioned your educational background, not much can be suggested.
