Can I include my spouse on my Green Card application?
In the employment-based category, your spouse generally can apply for a Green Card with you, presuming that your spouse is in the United States and in legal status.
In family-based categories, your spouse can come along with you as a derivative of your Green Card application.
In those cases, the principal, meaning you, is eligible for a Green Card because you either are in legal status or have been waiting outside the United States. Your wife or husband can come along with you.
In all other circumstances, your spouse probably can’t come with you to the United States.
