Thanks everyone for the input.

What about the chance if company provides me business visa and i then ask Qatar embassy in Beijing to provide tourist visa for my wife and daughter to accompany me on the "business trip"?

Is there a chance that would work? Qatar embassy must surely allow us to travel together as a family? What if we wanted to take a legitimate holiday there for example?

If they issue a TV - how long does that last for and how many times it can be renewed etc? Would it give me enough time to complete the RP WP and family visa etc?

Thanks again
