Canadians can enter and work on a TN visa, which has similar requirements to an H1-B. However, the number of visas granted is unlimited. They are renewed every time you cross the border, and can be rejected for any reason. They're very temporary and you end up feeling worried crossing the border. It explicitly does not allow a path to citizenship, so you have to transfer to an H1-B to get a green card. If your intent is to attempt to get a green card, you are in direct violation of a TN visa and can be deported. Unlike those jammy Australian bastards (they get a visa that looks like an L1! So jealous), spouses cannot work on the TD (visa for partners/dependents of TN holders). This means your partner cannot work if you're on a TN until you first transfer to a H1-B and then transfer again to a green card. For a Canadian, the process is probably 2-3 years to get an H1B, and then another 2 years to get the green card. Reducing the competition for an H1-B will reduce the length of time spent in the first step of this process. Indians and Chinese people have it much, much worse. The length of time after their green card approval to when they are granted one is quite literally measured in decades. The inability for spouses to work causes a lot of stress on relationships. Spouses get depressed, angry and feel a complete loss of independence. They no longer have a career nor their "own" money.
