you're welcome. yes, first they will check if everything is complete. from all the forms, down to all the documents they were asking in the checklist for the sponsor as well as the sponsored person before sending it to wherever your visa office is. i know someone who forgot to put some check marks, skip some dates(personal history) on their forms and didn't sign their names. CPC returned everything 3weeks after. visa officers are very strict when it comes to checking documents that are being received.
in my experience, i overlooked the checklist and i didn't send our CENOMAR or Advisory on Marriage. but fortunately and with God's loving mercy they didn't ask for it. like you have said, you have to keep your faith and stay positive. just keep on praying that all may go well with the processing of your application. because that's the most powerful weapon that we can use in all our endeavours in this life.
Thank you very much. I really appreciate it.
good luck. God bless
