Per the USCIS Poverty Guidelines for 2011, you will need to show at minimum, an annual income of more than 18, 530 for a family of three people. The amount of income that you will need to show depends on how many people you support; therefore, if you are also supporting your parent(s) or other family members, then the amount of income you will need to show also increases.
