Changing money is relatively straightforward. Banks will accept a variety of major currencies, while the money-changing booths that are ubiquitous in urban areas will typically only deal with US dollars, British pounds, euros, Russian rubles, and Kazakh tenges. Note that neither banks nor money changers will accept any foreign currency that is torn, marked, excessively crumpled, or defaced in any way, so be sure to carefully check any notes you intend to bring into the country for defects.
