Hey Saikat. Italy is definitely a smart choice as it offers good quality education at affordable prices. As a bonus it comes with roch cultural heritage and delicious food which makes your study abroad experience all the more amazing :) As for the CSE vs ECE question, CSE definitely has a broader scope not only in Italy but worldwide so just from a job point of view, you'll find it to be a better choice. But ECE in itself is a great branch which opens you open to jobs in some of the highest-paying sectors such as telecom. Make the choice depending on what interests you more and job opportunities will follow!

Great keep it up

Heyy there I would suggest you to look for Australia and New Zealand more for your approach as you have a better residency chance with lower costs especially in New Zealand and a great ROI as compared to Europe, USA or UK
