Guidance / Advice Needed

Hi Elpha network. Hope you all have had a good week thus far. I am thinking about the next chapter of my life and considering career opportunities in Austin, Texas (love hot weather and the tech-startup ecosystem there) with a company that is willing and able to sponsor me (I don't have a US work permit). If any Canadians in the community have gone through a similar situation and can offer some advice OR tips I appreciate it.
