Hang out at places that are known for foreigners and expats -- i.e. the local Irish/Canadian/American pub - there is one everywhere I've been from Italy, Spain, China. One thing I noticed from working abroad (or two
) and backpacking in my youth is that it is extremely easy to meet other travellers, especially North Americans - it seems the differences dissolve especially between us and the Americans as at the end of the day we have so much in common you'll end up gravitating together. You will also meet a lot of people in a similar situation as you, travelling alone for work/school and just want to meet people.
Building local relationships will take a little more time and it's really getting involved in clubs, sports, meeting them in class (work) and etc. No real appreciable difference than meeting new people here.
Good luck, it will be an exciting adventure.
