For what its worth I spent much of the last 20 years in Qatar and other middle eastern countries, but never assumed the job was permanent. So long as you understand that you can have a great life there - enjoy life to the full, but save money all the time and absolutely NEVER borrow money locally.
It is almost guaranteed that work overseas will come to an end unexpectedly, be it due to war, politics or another pandemic and if you are prepared its just another step in your life. I found myself laid off at the end of January by one of the major companies in Qatar & had absolutely no issues with them closing out bank accounts, arranging departures and end of contract payments to facilitate my exit.
