which city and state are you in and which city and state is your friend being represented??? I don;t know what to say abt the lawyer asking for 40%. You might want to contact Santosh Giri, a Nepali immigration attorney out of CA. He usually provides help to people here in sajha for immigration matter. Email him and ask for his opinion. His sajha email ID is santoshgiri. Hope this helps.

All the best to you and your friend!
