My wife is currently working on her H1B visa . As a dependent on my Green Card application she also has a valid EAD card and Advance Parole documents . She is planning to quit job soon . Once she does that , do we have to file for any change of status ? What will be her status then ? AOS on pending I485 or we need to file for her change of status to 4 visa as a dependent on my H1B ( I have a valid H1B too ) ? Any other formalities we need to fulfill ?
