One of my friends was mentioning that they have received applicants who have sent applications 2-3 times and that by NO MEANS have accelerated the process. It made the overall process slower as they still have to open the files which were under the pile, for the same applicant thus losing time for a new file to be re-opened. I know sometimes it's highly nerve-wrecking to wait on getting AOR, but instead of re-sending applications twice and thrice, my advise would be to wait and pray to God and follow-up with CIC instead.
At the end of the day you do not want others to fall behind and suffer consequences, because of your wrongful decision.
Just an opinion, decision remains with the discretion of the applicants waiting.
