Your family is going to move to another town Write a letter to the Principal of a local school asking if they will accept your son

Dear Sir,
My family is shifting to another town in Punjab. Currently my son is studying in 9th class in St. Joseph's school. I am writing this to you to ask for your permission to accept my son in the same standard in your institute. I will elaborate my case further ahead.
I am working as an Lieutenant General in the Indian Army. So, I need to move with my unit all the time and as per the protocol even my family needs to travel with me. Although, this is fun but it constantly becomes a reason for my child's school change every time. That is why I request you to allow my child to join DAV Public School from the 10th of this month. As, it will not hamper my pupil's progress in this session. He has already got his transfer certificate from the previous school.
Please grant permission for the sake of my kid's future.
Thanking you,
Yours faithfully,
XYZ
