When I was planning to emigrate, a number of my close associates expressed similar intentions. All of them are still in Singapore to this day and all of them are regretting their inaction when the opportunity to emigrate presented itself many years ago.
One of them went as far as to do to a
kepner tregoe analysis regarding the emigration process.

At the end of the day, his charts led him to believe that it was not the right time to leave so he stayed put.
I did zero analysis. I decided I wanted to leave so I took the necessary steps to make it happen. It was a very simple process. Forms took about 2 hours to fill. Getting supporting paperwork in place took a week in total.
