awkhan,

I don't think many people would think the deportation centre was a nice place. The Office of the UN High Commissioner for Human Rights has mentioned the problem:

Applicable international standards oblige Qatar to identify and treat victims of human trafficking as victims. However, domestic workers who flee situations of exploitation and abuse are frequently re-victimized. Their cases often fail to be investigated with due diligence by the authorities and the victims are considered to be irregular migrants whose visas lapsed once they fled from exploitative or abusive employers. In many cases these victims end up in a detention centre before being deported, while the perpetrators enjoy impunity.
