Hey Aspirant,

As per the admission rules for UG courses ,age is not a constraint.But for engineering and architerctural courses,the degree should be pursued by the candidate ,within 3 years after the completion of the diploma course.This is the law.

And it is clearly seen that you are eligible to pursue the course without any problem ,and also you have qualified the NATA examination ,you will be able to enroll into any college that has b.arch course in any state you choose to study.

Hope this helps.

Good Luck!!
