If u have a green card and if ur spouse or unmarried children under the age of 21 are legally present in US, u can apply for a green card on this august. On this august the date for 2A category are current so u can file both i130, i765 and i485  together. If u have all the required documents, ur spouse or a unmarried children under the age of 21 can get a work authorization card within 90 days and a green card within 4-6 months if everything went well. If u are not married yet, u can still marry ur gf/bf and file i130, i765 and i485 at the same time and will get a work authorization within 90 days and green card within 4-6 months. (Info given to me by a renowned immigration lawyer). I have no idea how it works if the spouse or children are out of the states since i didnt ask him(the lawyer) about it.
