Hellow guys, I am sajib from bangladesh. My wife is an US citizen and she is the petitioner for my immigrant visa. My interview was on 20th december in dhaka embassy and after the initial interview the visa officer kept my passport and gave me a blue 221g page and told me to return a answer sheet to some questionnaire so that they can do some additional processing. They told me that they will call me after the additional processing is done. On 21st of december I submit questionnaire page answering all the 10 questionnaire. I asked them when can I receive an update from them but they refuse to give me any exact date. So, does anyone knows , how much time does it take for this additional processing to complete. Its been 3 weeks and I haven't heard anything from the dhaka embassy.
