it's not clear.
what do you mean:"work visa will issued for 3 months and then it will be processed"... proceeded what?
Normal practice is issuing a work visa first, to make sure that the certain title, nationality and gender for the particular Company are approved by the Government. Then based on this Work Visa the Residence Permit for the particular person is issued, so that this person could reside long time in Qatar legally.
