I'd have to say that the fact that she is a female beneficiary has alot to do with her quick approval , Go Salwa!!!

. There are several reasons why I believe so. First of all, its quite common for a women in the Middle East to marry and come to the USA. Culturaly thats normal. Also when a man comes from the USA and asks for a womens hand, he usually does so with the permission of her family. Most men don't need their families blessings to get married. When there is family involvment, things seem more legit to the embassy.
I am not trying to offend anyone, but I am only posting my P.O.V. which even really applies to me since I am divorced.
Men in the Middle East and their families tend to want a bride that has never been married, has no children, and the families ofcourse want one of the same race and religion although. Obviously with new generations these things are changing. But from a Consular's perspective it really has not. They look at things from a general perspective and not that of the beneficiary.
Women also go through less backround checks than men do. There is obviously alot profileing done for certian relgions and backrounds, they can deny that all they want but you know when your name is Mohammed or Ahmed, etc that you are gonna go through some scrutiny.
Salwa didn't have very many red flags in her case. She is a woman (never married?), Full blown wedding with family pics, 3 visits, no big age difference, same religion, etc.
Again, I don't want to offend anyone, but these are just the general views of Middle Eastern people. I honestly never pictured myself marrying a Middle Eastern guy, especially after my divorce. I never even thought it would be acceptable, but I guess our new generation is changing.
