I have not, but I’ve done some immigration and have general advice:

Immigration is expensive and very time consuming to get the required documents.

• Figure out how you’re going to get residence, what visa you’ll be on, what visa your kids will be on
• See if you have to enroll in school ahead of time
• Test the job market by applying, interviewing, and getting offers beforehand. Even if you decline them, you don’t want to be surprised
• Make a spreadsheet of needed documentation for each person. Forgetting one thing can screw you up badly on the day you need it
• Do everything above, twice, to make sure you didn’t screw up the first time

Imo immigration is an amazing way to live the only life you have, but make sure you put in the work to make it work. I’ve seen lots of immigrants give up and go back to their home country before putting in the effort to fully realize their dreams, and it’s low-key sad
