I have a friend who is American and her husband is Israeli. They have been married almost two years. She wants a divorce but doesn't want him to loose his Business or his green card. What does she need to do to? They were married in Pa. How can she file so he doesn't loose his business or green?

Simply put the divorce on hold for a while. Divorce after he's granted a 10 yrs green card does not jeopardize his status

On average how long does it take to get a 10 year green card?

After receiving a conditional green card for 2 years, they must jointly file an removal of condition, I-751.
