Adjustment of Status is generally the last step in the green card process. In the context of employment based green cards, there are usually one or two steps before this filing. Usually either a Labor Certification (PERM) and I-140, or just an I-140 (like EB-1A, EB-1B, EB-1C, or EB-2 NIW) has already been approved. Employment based Adjustment of Status filings will initially be filed with a national office of USCIS and eventually will be sent to a local field office nearest to the home address of the applicant. Once at the local field office, applicants may be called for an interview. Historically, most interviews were waived for people adjusting status based on employment, but interviews were usually required during most of the Trump administration.
Generally, when filing an Adjustment of Status, people also file for an Employment Authorization Document and Advance Parole document. This card usually arrives quicker than the Green Card itself, and can give a person a form, or another form, of work and travel authorization while he or she waits on the adjudication of the green card.
