This is literally the definition of correlation, not causation.
No, that wasn't my argument. You're just making things up.
It's not just me who thinks immigration law is too complicated. It's anybody who has any idea what they're talking about. It was too complicated 4 years ago, and 8 years ago, and 16 years ago, etc. etc. Which is why for all of my adult life (and probably before then, but I wasn't paying attention) both parties keep talking about the immigration system being broken and needing to be fixed, but neither side agreeing on fixes. The audacity to pretend this is some new issue....
