My beloved daughter there has been so many cases of women being abused indecently until cases of rape in UAE and Qatar by the bosses of the private firms and businesses. Some by black mailing the girls other by giving them something in their drinks and so on. Horrifying cases. And since many of them get away easily without any proof and even if the girl complains she and her family get deported. So please be careful in whatever you choose. I think your father is not telling you the true reasons. Many foreign girls are oppressed and the law cannot do much. So of the low income families daughters are also given money to support their family and forced to do wrong and many of them do not have any choice except to accept.
Sorry for these bitter facts I know this because many share their pain to me.
