Colleges in Una

It is not specified yet that when will the campus is shifting because the campus of IIIT Una is under construction and will be fully functional in some 3-4 years.

Hi,
There is no direct scholarship program run by the Indian institute of information technology. However, you can avail many scholarships later for engineering students run by central and state government. Hope you got your answer.

In all honesty, it depends on the pace of work done at your institute. There is a slight chance majority of your degree won't be completed at your own campus, but highly unlikely that you'll complete 4 years not being at your campus.
Again, it depends more at the pace of work and how fast the government gives out clearances to your institute. I have seen some work finished in a jiffy (I study at a government institute as well) and some which has been going on for years and is yet to finish.
