You can do one of three things at this point:
- You can abandon your application. That is the DEFAULT decision if you don't do anything else.
- You can submit a written letter asking for reconsideration to the visa office. SAY "your reasons list that I have two children, but I do not have ANY children. I request that you reconsider my application. If I do not receive an affirmative response that you will consider my request within XXX days I will unfortunately be forced to file an appeal." (You want to force them to at least let you know they are considering your request, otherwise you will lose your right of appeal.)
- You can submit an appeal request. This must be done within a short period of time (check the specific CIC information, but generally the deadline is 60 days OR LESS.)
In parallel, I would also request a copy of your CAIPS/GCMS notes (search for "privacy" on the CIC website and you will find the "Access to Information" forms as the first link that you need to submit that request.) But because the appeal time period is so short, it's really important that you NOT let it pass - once it's gone, it's almost impossible to get it back (it's not *quite* impossible, but its not worth adding one more fight.)
Hmm. There's a fourth option: you could resubmit your application. Not exactly ideal, but it IS an option.
