I also have a similiar question. When do you exactly have to do medical? My case is going to be filed on EB2 so I think I-140 & I-485 is going to be filed parallel. What type of medical tests is involved? TB, immunizations, HIV...Drug Tests....Can someone who has been through the medical for GC answer please. Also do you have to goto the doctor your Lawyer specifies OR can you goto: https://egov.uscis.gov/crisgwi/go?action=offices.type&OfficeLocator.office_type=CIV and find a doctor close to you and do all medical stuff?
