My parents are trying to get their citizenship and I heard about the fee waiver. My parents file a joint tax return. My dad works, but my mom does not right now. My dad works as a limousine driver and is self-employed. What does USCIS look at on the tax return? Gross income is $73, 489. BUT since he is SELF-EMPLOYED as a driver, he pays for all his gas, tolls, car expenses, etc. Therefore, total income is $17,042 and adjusted gross income is $15,845. According to USCIS, for household with 2 people the income has to be $23,265 in order for them to qualify and get the fee waived. Do my parents qualify for the fee waiver for the us citizenship???
