1.Your husband won’t be able to sponsor you without a salary at least 7000 and a certain position in his Qatari ID.
2.You say, you "called your husband on Business visa". YOU cannot "call him on Business Visa"! Business Visa is issued by the Company or Private sponsor who is inviting a professional for the purpose of BUSINESS, not for the purpose of looking for the job. Do you know my dear that selling and buying Business visas is a CRIME? The one who sells you a Business Visa commits a crime. The one who buys a Business Visa commits a crime too, and once caught gets deported and blacklisted. Last level of carelessness is to announce whole Qatar about your “ability to buy a visa”.
