I am a Pakistan national and living in Karachi for 20/22 years and holding a Pakistan passport. Originally I migrated from Bangladesh to Pakistan after the fall of East Pakistan. My Pakistani passport was renewed a few times.
It expired about 2 years back. On Pakistani passport, I travelled a few times to Bangladesh. I am also holding National Identity Card and National Aliens Registration Authority Card. Yet the Karachi Passport Office is not renewing my passport for unknown reasons.
