LP, I don't understand why you keep arguing about the immigration laws, which obviously you have no clue about.
WORK visa was issued by the company, which he said he is not happy with!
And guess what, it IS possible to issue a work visa while the person is on the visit visa in Qatar.
You have being arguing about similar case just yesterday for few hours (Transfer from the business visa to the work visa)!
If your profession is Pirate, i don't argue with you on how to better rob or attack the ships in the sea. I am sure you are an expert in this. Right? So take my word, and benefit from learning based on my answers with regards to the immigration laws!
