Hi Suze,
This is very exciting!
I moved countries several times in my life and was always alone finding the opportunities and organizing it except help from employers; each time I moved for a new job and the adventure. The most recent one (~10 years ago) was from Europe to the US. Definitely don't regret it and this is where I've also made some of the strongest, most significant relationships in my life, although I do maintain a sort of cosmopolitan orientation as my identity.
Of course moving such long distance if stressful with all the unknown and uncertainty, but it sounds like there is a solid base waiting for you on the other side
Hang in there!
