We got ours back because we missed to fill out the visa office name. We were not sure what to do too, so we wrote down the visa office in the original generic application and attached a new generic application just in case. We also attached a new copy of the application asking for the NOC number, because as of Jan 31 they modified some of them.
I know its confusing but we figured out that it will be smarter to give them an option to decide which one they really want. Besides we were not sure if they have used the bar codes already as they have had penciled in a Unique Id No.
I hope this helps,
Good luck
thank you for your prompt response! we were thinking to do the same thing! hope it will suffice. thank you again so much, hope your application goes smoothly the second time around, (as well for us). just got back ours today, will be returning it immediately tomorrow.
