I submitted online application for citizenship truthfully detailing all my entries and exits. However this application was returned/rejected as my actual entry & exit data is not matching with that of CBSA's.
Re Online Application:
I do not know much about the underlying technicalities which affect making an online application. I suppose it is possible (I highly doubt it but allow for the possibility), that somehow an online application and the applicant's travel history is screened against CBSA entry records, and a discrepancy means the application is not accepted.
IF this is the case, there is NO fix that will facilitate making the application online. I doubt this is the problem, but if it is the problem your recourse is to make a paper application.
Beyond That:
I 94 is missing this entry as well.
If it mattered much, I'd ask is it an "
entry" into Canada or an "
entry" into the U.S., even though I suspect my understanding is correct, that you are referring to the absence of a CBSA record of entry into Canada for an occasion your records say you did enter Canada, and that the U.S. I 94 records similarly do not show an EXIT (from the U.S.) for that same occasion.
That is NOT nearly so uncommon as some suggest. While almost always accurate, the CBSA travel history records are not necessarily complete. There is a big difference between how accurate those records can be relied on to be (they are highly accurate, with only rare one-day-off errors), versus how complete they are. Given how porous the Canadian border is, and the extent to which entry into Canada can happen without the entry being captured by CBSA, either at all, or captured but not connected to a particular client's identity in the systems (multiple systems), IRCC is well aware that a PR may have travel history that does not show up in the CBSA travel history.
So the absence of a single date of entry record in the CBSA travel history will not, alone, determine the outcome of a citizenship application. Again those records are NOT dispositive.
So, the odds are high, just about overwhelming,
that is not the issue here (unless it is a technical element in online applications, which again I doubt but allow is possible, and for which the recourse is to make the application on paper). And, frankly, whatever communication you have received from IRCC I doubt that it states your application is returned or rejected because there is a discrepancy between your reported travel history and CBSA records.
More details may help the forum identify and illuminate what the issue is and offer ideas about how to address it.
As
@armoured initially noted, and I concurred, if the issue is a discrepancy between what you assert about your actual physical presence (and you are confident that is accurate), and what IRCC assesses based on other information (including CBSA travel history), ANY OBJECTIVE evidence of presence in Canada, as to the date in question, or the following days, should resolve that.
So, again, THERE IS SOMETHING ELSE happening here. Some OTHER REASON for the application being returned or rejected.
