You can get many private colleges such as LPU, Amity, Sharda, Noida International University, Chandigarh University, Galgotias University, Sikkim Manipal University, MS Ramaiah, Acharya Engineering College, Saveetha Engineering College, Kalasalingam University or Techno India University based on your marks in B.Tech mechanical, if you have given any other state engineering entrance exam/any other entrance exam like VITEE, SRMJEE or BITSAT see their result if you get a decent rank in any of the exam try taking admission on the basis of these, or you can drop a year to prepare for JEE Mains 2018.

You should appear for JEE Mains / state entrance exam of your state or you can give VITEEE, SRMJEE, BITSAT or KIITEE to get admission for BE in mechanical engineering.

Hi,
It's quite interesting to see that after BE in mechanical engineering, you would like to embrace either networking and software as a career.
If I get you correctly then your question is more of development and programming.
Python
Angular JS
Jason
Java
IOS, Mobile Development
IOT technology
These are in demand and have a good future scope.
Under networking, you may pursue CCNA and then move forward with professional or security domains. In parallel, you should think of Cloud Computing as well.

Yes, scholarship facility is available. ICCR provides scholarship for international students.

Hello Rahul,
As one grows older, chances of getting admission abroad become thinner. You have 9 years gap. So it may be difficult. But nothing is impossible. I suggest you approach a specialist agency dealing with sending students abroad.
