It will be several years after your sister-in-law files her petition, before you would be at the stage where you can apply for an EAD. As an F-1 student, you have options available which would permit you to work. Talk to your foreign student advisor at your university for information on that. Also, before you pursue a green card, I suggest that you consult with a competent immigration lawyer.
