I'm guessing Portugal must have improved a lot since I was there in 2019 and didn't have a great time trying to use English. I had better success rate with my extremely atrophied high school Spanish.
I’ve been to Portugal over 20 times in the last 10 years. In Lisbon and Porto, the Portuguese people speak English very well and most with an American accent. Foreigners who come to Portugal [1] and may work service jobs (a more recent phenomenon) may not speak English as well as the native population, while many of them still do still speak English well.
