Well, listen, there is such a great thing as TN visa, thanks to which I have been working abroad for almost half a year with my friend, who also picked up my idea. If necessary, I can share a link to the site
https://tnvisaexpert.com/services/renew-tn-visa/ where I made out. There you can see all tn visa requirments, and other useful information for applying for a visa and sending to work. I’ll add from myself that I really liked the work done by them, I advise everyone to contact them
