I get some regrets but realize its a choice and each path has benefits and drawbacks. I've missed loads of family, the big holiday house, my father is getting old, my childhood friends. I miss the lifestyle and culture. I dont feel American, my kids do though. I thought I'd move back after a few decades but now see that the children never will, which makes it another tough choice. My career here has been great, if it wasn't in a highly paid area I'd never stay.
