看了2011的貧困線的表，沒看明白。 自己是在48州的那個表裏的， 是說年收入是要多過1.25陪就可以了？比如說2人家庭，130% 是GROSS INCOME $19,564 就可以自己擔保了麽？
-If you are single and you want to sponsor both of your parents, then your household size is 3 (you plus your parents). Therefore, your total income have to be at least $23, 162 to be qualified for the financial support (I-864 filing). If your income less than that, you have to find a co-sponsor.
Using this USCIS data for the I-864:

如果是擔保父母兩人，這個收入可以嗎？
-See above.
如果找聯合擔保，是朋友但是不住在一起也可以嗎？
-Yes as long as your friend is a green card holder or US citizen.
