Err, your employer MUST know the process for issuing visas or they could't have gotten you a visa! Do they have an HR department? A mandoob? You mentioned QF, I'm pretty sure they can find out this process. Your employer must apply for a business visa for you. This may be granted if your employer has the authority to get a business visa for your nationality. Or did you come under a family or hotel visit visa? Then you can't change to a business visa without an employer who has such visas. Am I making sense here? And you need to find someone who can translate your visa to find out who your sponsor is. And BTW, PLEASE don't fall for buying a visa from someone on QL or in Doha. You really don't want to go there.
