Hi, if you are eligible for admission in Kamla Nehru College through first list and the last date specifies is 1st july, then all the candidates who complete their registration process and document verification by that day and the time specified, they would be offered the courses they have applied for. 

Try to complete the registration by that day itself, but if you miss the date, by chance you can apply when the next list is released but you'll be granted admission to the course of your prefernce only when all other candidates eliginle to apply through that list have completed their registration and the seats are still available for your desired course.
