I think Big Mama gave good advice.
I know things must be hard for you right now.

It's not fair to you that you lost Yousef because of something that was absolutely out of your control. But I think ultimately the best thing you can do for yourself is spend a little time trying to get over Yousef a little more completely, you know? I know how much easier said than done that is, believe me I do. But it's not fair to you and whoever you decide to have a relationship with if you're still haunted by Yousef's figurative ghost in your heart. I don't think, given how sudden and how harsh his loss was to you, that it's possible to have gained any sense of closure with it. I know at the very least I wouldn't have.

Time, I think, will help heal that wound.
I wish I could help you more with the embassy and immigration laws with Hussein, but that's outside my realm of knowledge, even as a prelaw major.

Frankly, they're a mess at best. I do share your outrage over how generally unhelpful they seem to be though. :/
Also, for what it's worth, I understand entirely what you mean about being hesitant to tell about online relationships. I have been in 3, and each time it was always an awkward affair telling my mom. I love my mom to death, and we have a great relationship, but I couldn't help but sense her dissatisfaction through the smile.

I think, though, that it's ultimately for the best to be upfront with your parents about it. Honestly typically is the best policy, cliche as that is.
I hope I was of some help, and I hope things work out for you.
PS: Do pardon my curiosity, but it caught my eye and I had to ask. What does
Ya Rab mean?
