In short yes, u will be able to gain employment in Qatar, as long as u will be on your husband's sponsorship. The advantage u will have being on ur husbands sponorship is that if u are not happy with ur job, u can always leave and join another company.

When u arive here go to keyresourses and they will test u and forward ur cv to some of the major companies in Qatar.

SO not to worry.

Regards
