Buenos Aires, Argentina

Capital City

With a population of 3.1 million, Buenos Aires is a bustling, cosmopolitan hub - but also a reality check for Americans seeking a new life abroad. The city's thriving arts and cultural scene are undeniable, but residents face a persistent bureaucratic headache and must contend with the region's volatile weather patterns. Overall, Buenos Aires is best suited for those with a passion for European-influenced architecture, tango, and the sheer energy of a global metropolis.
