Not sure where you're going here. I don't remember mentioning Canadians.
You didn't have to, that argument is used often in columns and TV shows. We have ranging from 6 to 11 million tourist visas each year - a little lower during pandemic years - and that oft quoted argument is little more than an accounting error.
I used to wonder how in the hell we could be so lax when it came to tracking LEGAL entrants to our country - so I began a deep dive into the numbers. We actually do a GREAT job tracking them - the percent of those NOT accounted for is pretty small and fairly consistent. But, it adds up and by all accounts, the persons who appear to NOT go home, eventually - DO. They're not here. They left, we just *missed* them.
And the easiest way to see that without digging trhough piles of visa applicants is to look at the nation of origin of most of them. The largest portion of the total of persons who appear to overstay their visas and by first glance, seem to remain here - are from Canada and we KNOW we're not swimming in Canadians. So that quoted stat has no value - it's just somethign people say to deflect from the issue.
We have, within the last two years, an estimated 1.5 million "gotaways" that we know of - obviously there are more that we have no clue, because not everyone who sneaks across the border is seen but escapes. THAT number is the estimate from seen encounters. The number of illegals sitting in the country awaiting their day in court - should they ever appear - or are ABLE to appear - is more like 6 million since Biden took office.
More evidence that the "overstay their visa" argument is moot, because at this point, it would have to be ALL of them - we only issued a couple million last year.
