Yeah i travel on Pakistani passport and i prefer to travel with groups. I never hide my identity and always follow the immigration rules and cooperate with officials. Before visiting somewhere i read carefully their immigration laws and culture.
I believe and experienced that no one hate Pakistani or our passport. Its our behavior & attitude who made us mysterious and lead us to point where we are. Example when our people travel from Europe or US or even Dubai, they bought many unnecessary items which are already available in Pakistan even with better quality. When custom or immigration officers examine your luggage they feel discomfort and this discomfort change their behaviors. I always travel with very less luggage and Alhamdolillah never asked to open it.
