Police verification adverse report after getting passport

Dear Sir, I was a student when I applied for a normal passport in 2012 from Cachar district, Assam, while my hometown is Jorhat district in the same state. The passport was issued by RPO Guwahati in 2013 after police verification in Cachar police station but it was given an adverse report only today (19th April 2017) in Jorhat police station due to my unavailability for second police verification, as I am currently living in Bangalore doing my PhD. Jorhat police station had called me on phone earlier but I requested for two months time due to my ongoing studies in Bangalore, which they agreed. I have not received any official letter of adverse report but only been communicated by the Commissioner's office when my parent's visited the same to ask for an extension on the verification process. The police said they had to go back on their promise of allowing me two months due to some official pressure. Please let me know of the procedure that I should follow now. I have an upcoming travel to US for an internship related to my studies and am worried. Thank you very much
