While large cities such as Berlin and (to a smaller extent) Leipzig and Dresden have become multi-ethnical and have large immigrant communities living there, in smaller cities and in the countryside, non-white visitors might sometimes attract wary looks. In some places there are right-wing Neo-Nazis, which may look for trouble, especially when drunk in the evenings. Act with common sense, and in doubt stick to bigger crowds of 'regular' people. Don't be afraid of calling the police when feeling uneasy. Sadly, not all hate crimes are committed by Neo-Nazis.
Employees of German companies are normally assigned a tax class by the tax authorities according to various categories. The "Tax Class" ( Lohnsteuerklasse or Steuerklassen in German) is important in determining the amount of withholding (income) tax deducted from a salary as well as in determining the value of a number of social benefits for which the taxpayer may be eligible. A tax class may be assigned to an employee by the authorities based on marital status and other criteria. In some cases a taxpayer can request to be placed in a certain class.
