ok..

you should always book a two way ticket for a tourist visa..anywhere in the world.

now if u have a tourist visa to qatar go ahead and book two way ticket. for one month.

now when u are here in qatar..ur husband should finish his paper and ikama with his sponsor.

he will make a non objection letter to the immigration department from his sponsor to let him start your family visit for six month.

in this time when the letter finish u should get a NOC from the hotel with no objection and u will b on your husband sponsorship after finishing the new family visa from immigration department....

after all this..u should pay 500 QR to switch your visa from tourist to family visa...and u should finish all this during the one month validity of the tourist visa.

the immigration gives u first one month visa u can renew it later for 5 month after doing the commision and blood test ..

NB: U SHOULD FIND A HOTEL WHO CAN GIVES U A TOURIST VISA AND LATER GIVE U AN NOC LETTER WITH NO OBJECTION.
CZ MOST OF THE HOTEL HERE DONT GIVE NOC.
LA PALACE HOTEL WILL GIVE U NOC HIS NUMBER IS:44367301

IF U NEED MORE INFO LET ME KNOW.
