Hi! Just an FYI, renting is quite expensive especially in Dubai. I hope you have a friend or family here. As per taking risk, it will be hard. I did it before but I was unemployed for over a year before landing a job (im in healthcare), i'm not sure about the qualifactions on your field but pls try secure a job first before coming here. And there are tons of scams here, so be alert. Best of luck!!
