Hello Aspirant
Yes, you are eligible to apply for second-year BTech admission at COEP Pune as a Jammu student.
COEP Pune, like most engineering colleges in India, accepts students from all over the country. There are no specific domicile restrictions for admission. If you are already in a BTech college, you will have to transfer your credits from your current institution. But COEP Pune is a highly competitive college. You will have to meet the college's eligibility criteria and secure a good rank in the r JEE Mains to get admission, even if you are transferring credits.
Hope this helps
