I don't know what a CUSMA visa is - I thought CUSMA was a trade deal?, but it seems very convenient to compare the standard Express Entry points-based immigration track versus (nothing) on the US side. Convenient is an euphemism, reality basically the opposite of what you're saying:

Moving to Canada:

- Rational points-based immigration system with transparent rules which you can actually look up and prepare for, start your life as a Permanent Resident with all but voting rights compared with a citizen, become a citizen in a few years.

Moving to US:

- Wait years for an H1B with a yearly lottery with 15% chance

- Wait another 10 years for a Green Card, equivalent to a PR card - Wait another ? years for full citizenship
