few obstacles to transition and assimilation into mainstream society; culture shock for Afghan Pashtuns is relatively small in parts of northwestern province of Khyber Pakhtunkhwa and the northern parts of Balochistan. In 1997-2001, Pakistan was very bias towards Afghan refugees that they threatened to shut down the border and forcibly return Afghan who had the right to be there under asylum. Similarly, Hazaras from Afghanistan can easily assimilate due to the presence of Hazaras in Balochistan. However, this is not the case for the Tajiks from Afghanistan.
