USCIS has created a new online tool to help green card applicants find doctors authorized to provide the medical examination required for most applications for adjustment of status (I-485s). The website provides the names and contact information for authorized civil surgeons in the area based on the address or zip code. It also lists what documents applicants should bring to their appointments and briefly explains the medical tests conducted during the exams.
