Как вызвать родителей в США (Кира)

What are the income requirements for an Affidavit of Support?
....Your household size includes you, your dependents, any relatives living with you, and the immigrants you are sponsoring. For example, if you have a spouse and two children and you want to sponsor your brother and his wife, you must prove that your household income is equal to or higher than 125 percent of the U.S. poverty level for a family of six, or $30,850, from the table below. You must also include in your household size any immigrants you have previously sponsored under this part of the law. In the above example, if you had previously sponsored your parents and your sister, your household size would be nine persons and you would need a household income of $42,625 ($38,700 + $3,925).
