@ divyang ji,
Please go through the fee payment para in the of IMM CARRYING details thereof.Without payment of "APPLICATION PROCESSING FEE", I wonder,how would ur application be processed. In fact, u run the risk of application being returned unattended on account its being incomplete.However, payment of "Right to permanent residence fee" with the application is optional. Generally, Visa processing office, which is designated to issue visa after approval of application, requests for it after the application has passed through all level of the processing system.
Hope, this ma suffice.
Good luck nd MAY God bless all !!!
