Engineering in India

Yes, America is a good option to pursue aeronautical engineering but you should not rule out the option of studying from India as well. India is a growing country in this field and people are getting very good pay as well. I can list down a few colleges I know of in India:
• Indian Institute of Aeronautical Engineering, Dehradun
• Indian Institute of Space Science and Technology, Thiruvananthapuram
• PEC University of Technology, Chandigarh
• Sathyabama University, Chennai
• UPES, Dehradun

In top IITs, the highest package offered is Rs.50 LPA, depending on your capability.

If you are planning to go for higher studies after B.Tech, then opt for electronics engineering. Electronics engineering has very narrow scope in India. You should opt for B.Tech in IT or CSE instead of electronic engineering.
B.Sc in IT is also a good course, but you will get benefited by pursuing B.Tech.

Here are the top 5 colleges:
IIT Madras.
NIT Trichy.
Hindustan (Chennai).
Madras Institute of Technology.
PSG Colleges Of Technology (Coimbatore).

Hello Gurjot,
India is far better than New Zealand for computer engineering. In India, there are lots of good universities which will give you good placement after successful completion of your engineering degree. You can go for Masters in countries like the USA to avail better career prospects.

Yes, you can take admission in BHU, Varanasi for this course.

I don't think options are available in US , you will find only MS or integrated Ph,D , graduate certificate courses are available in few universities but you need to hold an advanced degree for the same. If you are not interested in Masters there is no reason to prepare for GRE. Instead look for PG Diploma courses in Australia, Canada or New Zealand. You need to decide what you want to study and prepare accordingly. Check University of Michigan - Dearborn, University of St. Thomas, Minnesota and Boston University for Graduate Certificate in Engineering disciplines. Best of Luck.

Indian Maritime University (IMU) Chennai , Vels Academy of Maritime Studies Chennai and International Maritime Academy (IMA), Chennai are the best
