Thanks Cherr1980 & Jim Mills,
I didn't give a clear picture of my friend's situation, and I thought NJGIRL assumed my friend's husband had included my friend in his application. They submitted the application through his company attorney, so all receipt letters were at husband's hand. She only got an approval notice of like "I539" expired August, 2006. She is sured that her husband had filed her I485 too. Then she is AOS, not H4, can she apply for SSN or EAD? They didn't live together but her hushand helped in renting a place for her and everything. If she has SSN and EAD, she can be independent on him. Another question is she has an USC boy friend now and intends to divorce her husband and re-marry. But her husband begged her to divorce later, after GC approval, as it will be soon. We are wondering which case will be faster.
