When should I expect to hear back from an agent?

Good day, 

I have applied to four different jobs as listed under Teachers in UAE. On the dashboard page it does show that my application has been submitted. How long, roughly, will it take for someone to inform me of whether or not I have the job and whether or not I qualify for an interview? 

Please will someone also let me know if its possible for my husband to relocate with me. I dont have any children but my husband is also looking for a job there and wants to relocate and live with me should I be accepted by one of the school. We would hate to live seperately. 

Thank you so much for all you support and guidance! 

kindest regards,

Victoria Baker
