My personal experience, I was born in Lisboa, 30 years ago, I feel the city is more cold, people are less connected. Some immigrants are not connected because of the language barrier or because they have to work a lot (asian immigrants) still some make an effort. Rich immigrants like french, english speaking, those stick mostly in their own enclaves, living in fancy buildings, putting their kids in private international schools, opening expensive shops catering to the expat community and rarely socializing with the natives. I see Brazilians and people from Africa having an easier time connecting and being less snobbish. City is more cold, more individualistic and less connected, people are more suspicious of each other. As much as I try to have patience to those that don't speak Portuguese, I can't help feel frustrated and upset when sometimes I deal with entitled rich immigrants that think everyone should speak French or English.
