Forbes has released some interesting news on the above topic. It is little old though, I consider this to share here. "The country that once welcomed the tired, poor, huddled masses is now asking for a little reciprocation. And Canada, Germany and Australia are heeding the call. They top a list of the countries most welcoming to expats. There, relocators have a relatively easy time befriending locals, joining a local community group and learning the local language. Canada is the most welcoming; almost 95% of respondents to HSBC Bank International's Expat Exploreer Survey, released today, said they have made friends with locals. In Germany, 92% were so lucky and in Australia 91% befriended those living there. The United Arab Emirates was found to be the most difficult for expats; only 54% of those surveyed said they'd made friends with locals."
I am not sure about Germany, but Australia and Canada are definitely great countries to be in. Not been to UAE, but Japan and China aren't really that receptive to foreigners, maybe friendly to tourists but not if you are living there for sometime.
Most people from countries like poland and germany are normally very rude and dont believe in waiting in line ect I would agree with australia and canada though , i also think that france are one of the most unfriendly countries
I have my relatives in both Canada and Australia and most of them agree that both the countries are truly very friendly.... The local citizens are just very co-operative and always willing to help... Regards, RightMan
