Generally speaking, a medical examination submitted in connection with an application for adjustment of status is valid for one year. Due to visa backlogs and expanded processing times, many adjustment of status applications are not adjudicated within one year of filing. In January of 2006, USCIS extended the validity of medical exams until January 1, 2007. Due to the continuing backlog of some adjustment of status cases, USCIS has extended the validity of all filed medical exams until January 1, 2008. In other words, medical exams will remain valid until the adjustment of status application is adjudicated or until January 1, 2008. There is an excellent possibility that this deadline will be extended again the future.
