I have got no reply of my two requests, i have got the reply of my third one. The reply was regarding the missing document of my file.
After completing my all the documents, getting sign's on all of my documents i submitted my file by visiting my school.
It's been a month again i have got no reply. Please sir/ma'am it is very important to change my mother's name.
Due to my some schools documents my passport process has been stopped and it's very difficult for me to wait it's been a year that i am facing these difficulties. I had also made my Gazette document in which it's clearly mentioned.
I will be very very faithful to you sir/ma'am if you changes my mother's name. If there is another process then please notify me by replying on this Email id or contacting on my phone number [protected].
You faithfully
Kamal jeet Singh
