Salamo Alekum sister Farhopes
May Allah reward you the best for your efforts..
Being Egyptian myself, I know how issues are conducted in my country.. I'd say no for "Police" and " US embassy" suggestions..
Actually I'd rather stick to the verse that states :
"If you fear a breach between them twain (the man and his wife), appoint (two) arbitrators, one from his family and the other from her's; if they both wish for peace, Allâh will cause their reconciliation. Indeed Allâh is Ever All¬Knower, Well¬Acquainted with all things." (35:4) An Nesaa'
And as in your case it's almost impossible to appoint an arbitrator from her family, I strongly recommend the suggestion of getting the help of a local imam or sheikh (who must be respected and honored by the people of the region especially by the family of the husband) to talk on behalf of the wife..
You have always to keep in mind all through your god-blessed trials that the priority is to trying to repair, or to mend and heal the relation between them, for Allah (subhano wa ta'ala) says:
"And if a woman fears cruelty or desertion on her husband's part, there is no sin on them both if they make terms of peace between themselves; and making peace is better......" (128:4) An Nesaa'
And that He describes the contract of marriage as "a firm and strong covenant" (21:4)
remember; making peace is better
BUT, and if all the trials are to fall, and if this man is really bad and is really abusing her and has not any intention to change the way that's harming her, then Allah (subhano wa ta'ala) states:
"But if they separate (by divorce), Allâh will provide abundance for everyone of them from His Bounty. And Allâh is Ever All¬Sufficient for His creatures' need, All¬Wise" (130:4) An Nesaa'
In case he refuses to divorce with kindness, surely he's disobeying Allah's orders: "..either you retain her on reasonable terms or release her with kindness.." (229:2) and "..either take them back on reasonable basis or set them free on reasonable basis. But do not take them back to hurt them, and whoever does that, then he has wronged himself..." (231:2) Al Baqara
And in this case, I strongly second the suggestion of suing for divorce (divorce and not khul` خلع at first not to lose her rights) and if this didn't make it, it's ok for khul`, and if she doesn't have enough money to make it, pls let me know, I think we can work on it...
May Allah help us all and guide us for what's best
