Please note that the complaint should include as much information as possible including: the name of the consulate where the incident occurred, the date you visited the consulate, the time that you met with a consular officer, the physical appearance (or name, if possible) of the consular officer (sex, approximate age, hair color and other distinguishing characteristics), the window number at which you met, and a detailed explanation as to why you believe you were treated poorly. They recommend you provide your name, case number if you have one, and passport number. A complaint may not change the outcome of your case, but it could affect the actions of the consular officer in future cases.
