The boss said that the company was going to move abroad, and everyone had to go there, otherwise they would make their own arrangements. What do you think?

look at your own situation. If a company wants to move abroad, it should be possible to develop. If you have no other external factors that prevent you from going, you can still go. After all, a promising company is still worth fighting for. Of course, if you have concerns, you should find another company to work for. I believe you are also a very capable person and you should be able to find a good job again.
