For the income amount, do you mean the requirement of the sponsor?
Moving to the US with a spousal visa requires the Egyptian to be sponsored, either by one person or several individuals together (however the income requirements are met). The minimum income amount changes every year, according to the rate of poverty. When I brought my husband here it was around $19,000. Which meant that your sponsor had to have made 19k a year for the past two years.
For us, they asked things like "How long have you known each other? Where did you meet?" and just other questions that were about things that should be simple for people who really love each other to answer. That's during the interview process.
