Sneaks - i think your post is quite presumptuos.
1) Where I am from needn't matter.
2) My post has little to do with my kind of phd. And am not doing any interviews FYI.
Sorry Jojo, didn't mean to be presumptuos, although I think maybe where you're from may matter in terms of people's expectations and initial reaction to you, which may have affected (whether consciouly or not and/or rightly or not) their warmth towards you. tbh I only said US, because Jojo sounds a bit american but I suppose I was jumping the gun a little.
I was just enquiring about in what kind of situations (you mention appointments) you have to meet people, which may help us understand a little bit more about how you're feeling.
I know my actual contact with participants was horrendous - I am from the same country, just different ethnicity, age, background and I was very much treated with hostility and suspician. Thank god I have got it over with! But I still experience it when trying to provide feedback to stakeholders :-(
