Language
Most trafficked women do not speak any or speak very little German / English. Many people believe that a prostitute who does not speak the language of the country is a trafficked woman.
This is not true. Like in any other profession, there are women who work in prostitution and who know very little German / English or none at all.
Remember:
Women who dont speak your language or any German or very little may need a translator. Take a dictionary with you.
