Ah Mate!
Don't know how old you are but I was 37 when we decided it was time to take the family overseas for what I expected would be 2 years. Daughters were 9 & 12 when we moved Down Under. (Start to finish it took 10 months to get a work visa in 2007)
I wrote my epic novel on things you need to consider here:
https://texags.com/forums/56/topics/3116157I originally wrote that during early California Covid so I'll re-read it and see if I've got anything else to add now that I'm safely wedged into Texas for the rest of my life.
On re-read, given the fact that we're in a US Election year, expect to get a lot of questions about US Politics. Either about Donald Trump should he get elected or Kamala Harris should she get elected. Foreigners will be curious either way.
I went to Austria in 2003 and moved to Australia in 2007. In both situations, I got lots of questions about George Bush and the war in Iraq.
Otherwise, I can't emphasize enough that you need a plan for how you're getting in - work, school, funding, etc. And also a plan (ironically since I just mentioned the US invasion of Iraq) you need a plan for how and when you're getting out.
Lastly, you need to be committed to the cause. I've seen a lot of Americans go overseas (both to Saudi Arabia and even to Australia) and they don't last a year. First sign of difficulty and they're gone.
I had an American girl in my office in Sydney who couldn't deal and among her complaints were the fact that they didn't have items she was used to like - Crest toothpaste. I really had to keep from laughing on that one.
Another American guy struggled and was gone from Sydney after 10 months because he wasn't committed to building relationships. He expected things to be much more transactional. You put a good business value proposal in front of the customer, they spend a few million dollars with you. And that's not how the Australian culture works. They're not obsessed with the bottom line the way US corporations are.
I was successful in stopping one guy from transferring to Sydney (from our office in KC, MO) once I explained to him that he wouldn't be able to bring his Honda Odyssey mini-van. That was the deal breaker for him. Also, there was the bit about paying $5,000/yr per child for his 5 kids to attend the public school. So he was starting out $25,000 (after tax dollars) in the hole every year as an expat.
