Q: How do I change my App Store locationas I have shifted to a new country

Greetings Prateek707,

Welcome to the Apple Support Communities!

I understand that you would like to change the country of the iTunes and App Store on your iPhone because you have moved. To complete this change, please follow the instructions in the attached article. 

Change the country of your iTunes Store, App Store, iBooks Store, and Mac App Store account - Apple Support

Cheers,

Joe
