America. Honestly, Americans are friendly and fascinated by foreigners. I will give you some evidence if I remember but they really like people from the Anglosphere.
Let's avoid expat mentality because I'm assuming you're asking as an expat.
Speak the language. If not, get out of your compound, foreigner mentality, etc. Learn bits about culture there, and express interest.
This is all anecdotal:
Canadians seem great, they are warm people who are extremely agreeable.
Serbians are awesome to me. They are super open to meeting foreigners, but again, I met almost everyone through social circles.
Brits seem really chill to have a beer with, but it always fizzles from there.
Germans in Germany are not chill at all. Meet a German traveling and they are super nice.
Central/ South Americans seem pretty nice and warm, and most importantly, laid back.
Middle Easterners (we're talking about a large region here, just like C, SA), can be great if you meet them abroad, and express your interest in ME affairs. I've found they're super nice, polite, meeting them in the states.
