For JELET there is no domicile requirement. So if you wish to take admission through JELET, then you are eligible for it. Now if you have completed your Diploma in Engineering in any field, then only you can take admission to the 2nd year of the BTech at JADAVPUR UNIVERSITY.

Now if you want to study at Jadavpur University being a non-diploma student, then you have to qualify the WBJEE examination and you have to take admission in the 1st year of the BTech/BE in the Jadavpur University.
