I am trying to understand the appeal process for I 751 good faith marriage waiver. I am aware that once an immigration officer denies a waiver petition an immigrant can go in front of the judge followed by Board of Immigration Appeals. In case Board of Immigration appeals also denies the waiver. Are there any further courts or elsewhere an immigrant can appeal? How much time does it take in the whole process i.e. how much time does judge take to make a final decision, how much time does BIA take and so on?
Thank You for your time.
