Help Needed

Hello Ql Members,

I wish to bring my Cousin Sister to Qatar for family visit visa for job searching.I enquired about this to many people, all of them told that it is possible but for only 1 month & cant extend upto 3 months in family visit visa.

But i saw in this site
(http://english.mofa.gov.qa/visa.htm),

other relatives can renew 2 more months(Total 3 Months.)
Is it possible, if possibe what are documents i needed to take it.

If i cant take family visit for 3 months what is the other option that she can stay here for 3 Months.??

I heard about business visa also?How much it costs for 3 months, i only need only visa,because she can stay with us.
am also new to Qatar so don't know much about it. Pls help me in detail for sort this probelm

All helps are highly appreciated.

Thankyou all
