You need to show the visa copy and submit original passport to Qatar embassy in Philippines for stamping. After a week it will be stamped in the passport and then you can fly to Qatar. As per the new rule, all business visa should be attested and stamped by Qatar embassy in Philippines. We recently got a new staff on Business Visa and did the same procedure. Earlier he was not allowed to board later after stamping his visa on his passport he was allowed to travel.
