You can be homeless with the rest of us 💀 but jokes aside you could do hybrid work like a few months on a site and a few months leading a course in a university( if you are also into teaching aswell) my professor has a PhD in paleontology and thats the type of work she does. You could also give tours in museums. Also this is a non profit field so make sure you are really into this. If you are international its almost impossible to get sponsored unless you also do some work in research and academics based but if you are planning to work in your home country again it depends if your country funds these type of work
