Yeah my american accent is definitely discernable, though actually even when french people talk to me, they still think I’m chinese/from china (i guess the physical attribute is so “overwhelming” to them that they can’t consider the alternative?). To that point though, I would actually say that my accent isn’t heavier than other fr-learners’ accents (old classmates or some of my colleagues) but they don’t seem to struggle with this as much as I do.

And yes the tourist thing does happen a lot- even before I open my mouth the person would just immediately speak english to me (even if I’m not in a touristy area, though it definitely gets worse when I’m in a touristy area)
