How many immigrants are allowed in is orthogonal to whether the process is efficient and direct. The process is insanely complicated and takes years and no small amount of luck, or dodging arbitrary discretionary decisions by mid-level bureaucrats. Reforming the process entails nothing about whether that means more or fewer legal immigrants are allowed in, and removes a huge incentive to bypass the process.

In a previous job I helped H-1B cardholders get green cards. I kept getting applicants approaching me saying that they could get one easier with $5,000 in Chicago than waiting all this out. It was hard to argue against that.
