hi.. i send in the application of sponsorship for my pregnant wife and it got returned beucase of couple missing documents and a signature ( i am so dumb) but one thing i don't understand is they are saying i have insufficient processing fee. they sent me a piece of paper with highlighted part saying that. also they wrote down "separate processing fee receipt required" i am really confused here. i totally paid 1280 for family sponsorship , open work permit and Right of Permanent resident fee. for my understanding is the right amount. does it mean i need to pay again? because it got returned? please help !
