for the purpose of job hunting like what others say its very risky and there is no assurance you can find a good job and obtain a working visa my employer lied to me and promise to transfer my business visa to working visa but they failed to do it and i renew my visa twice on my own expense and still they failed to help me to obtain a working visa thats why i have no choice but to go back to my country and before i came here in doha i know those consequences like nomad say no guts no glory and ive learn from my mistakes but still its the choice of everyone to find there luck for there future and its the reality of life and there is no reason for this IO to hold those people having complete documents to travel.
