after completing 1st year in a college then We can admission in 2nd year in other college or university
Sorry but whatever you just asked for is quite impossible, i.e. after completing 1st year in a college, you cannot take admission in 2nd year in another college/university. To take admission, you have to again go through the college admission process and get yourself joined as from 1st year only. Earlier wherever institute you got joined in the first year only, continue with the following years as well in that same institute only. But as I've said, you cannot change your college and get yourself joined as a 2nd year student in another institute like that. You need to give a proper reason so as to change your college.
Hope, this answer helps you.
