How to Relocate to US as a Foreign/International Startup Founder?

Basically the title says it all. We are 2 engineers, we are interested in moving to US so we can access the North American market. We have already checked E-2 investor visa [1], but unfortunately, we don’t qualify. We found more information about Canadian startup program [2] as well, and we are checking it.

We are planning to apply for startup programs (e.g. YC, Techstarts, etc.).

Question: (1) Is there any way we can prepare for this?. We heard various stories from international YC founders, but how do founders do it?. (2) If you see that Canada is a better place today, please let us know why?.

Any help appreciated!
