no, i haven't entered doha on 'different types of visas'. in 2005, that was the only time which i had a working visa stamped in my passport, and i entered doha. in 2006, the residence permit/visa was cancelled upon my resignation from my job, then.

between 2006 till today, my entries into Doha, were based on visit visa obtained on-arrival at the airport.

that business visa which was applied by a Qatari company, this year, was never been used. it was cancelled by the company upon my request and an NOC was given to me. this NOC had also been forwarded to my new employer to fulfil the requirement of immigration for my new work visa under a different employer.

i'm still not getting a good feel from the ground of what could be the possible cause of this delay now, or under what circumstances would my new work visa be eventually not approved?
