I dont think you should have re-sent. Its just a delay because of the number of applications. But its your personal decision and I respect that. I dont think it should be a major issue though. Good thing that you have put a cover letter.You have no idea what you are talking about most of October applicants got Aor, only few didn’t get it. We are not sending 1000 applications. I waited 3 months and specified in the cover letter if in the mean time the original was found to disregard the second one, at the end of the day we are dealing with adults here that get paid to do their job not some kids trying to prove something.
Also a lot of cic agent are immigrants and probably went through all this too ..
I am positive that all those who have re-applied will get their AORs for the 1st applications. Keep us posted on the progress. I am curious to know what happens. All the best to you guys.
