The availability of tourist facilities and services is uneven throughout the country. Travel is unrestricted but be prepared to show your passport to police on demand. There is little street crime in Ukraine, but when incidents do occur, foreign visitors, perceived to be wealthier than local residents, are usually the targets. Americans of African or Asian descent have occasionally been subjected to racially motivated harassment. In the case of Asian-Americans, complaints have centered on being repeatedly stopped on the streets by civilians or police. Credit card and ATM fraud is widespread, so use of both is not recommended. Ukraine has a cash economy, and money scams are common.
