I am concluding my Ph.D. in the UK, and currently I have two postdoc offers one from the US and one from France. I am not a British/EU citizen and would like to take on an academic path preferably in an English speaking institute. Both projects that I managed to get a postdoc offer for are very interesting, and the PI's are well-known academic in the field.
Given that becoming an academic in France requires fluency in French, I was wondering what would be a wise choice here? What are the general qualities that are important for a lectureship position? I am under the impression that for STEM fields, USA is a no brainer, but acquiring a visa might be difficult for me!
Any advice is really appreciated.
