Subject : Adverse report by Police - Address verification, regarding Sons Passport, Renewal & Change of Address. Subject : Show Cause Notice by Regional Passport Office, Madurai, Adverse report by Police - Address verification, regarding Sons Passport, Renewal & Change of Address. My Son Applied for Passport Renewal & Change of Address. Our permanent address is in Tirunelveli, Tamilnadu, My Son's Aadhar, Voters ID, Ration Card is at the permanent address in Tirunelveli. He is employed in Bangalore for the last 16 months and is temporarily residing in Bangalore. While interview at passport Office, Tirunelveli (under Madurai) he did not mention that he is currently employed in Bangalore. Reason : 1. he is not allowed to use his mobile during office hours and so will not be able to attend to any calls during day time. 2. at the time of applying for Renewal & Change of Address he was seriously anticipating quitting his current job and was not sure where his next job will take him. 3. I am always accessible over phone and in person at our Tirunelveli address. At the time of police verification since I was at home in Tirunelveli, I informed the police that he was employed in Bangalore and on their direction, I also provided them the appointment letter dated 16 months ago, this fact has been mentioned in the police report. Now the Regional Passport Office, Madurai has issued a notice to my son asking for clarification as to why he suppressed this information and why action should not be taken to impound the pasport etc..etc.. Please advise what my son should do now.
