You are right. Sending your résumé along with Certificate of employment, ielts result and training is advantageous and easier for the interviewer to decide on your application. It is even better if you will also include you spouse credentials. That is what I did last year thru mpnp exploratory visit. I sent them my request and they responded immediately positively by accepting my request to complete the exploratory visit. No further questions asked and no additional docs requested. They simply told me to give my schedule for the visit. Did my exploratory in July 2012 and received my loa dated
nov. 12, 2012.
My application is now in CIO. Good luck all. May The Lord grant our hearts desire.
