我本人是綠卡持有人，本次是準備為持B1/B2入境美國的太太及未成年孩子申請485，我目前在美國的賬戶上有一些股票，也有一些存款，我太太在中國也有存款與房產
-Unless your spouse bring her assets as cash to US, her assets in China cannot be used for I-864.
，那我是不是提供我本人的股票持有證明或我的存款證明即可？（不需要另外再找第3方擔保？），是不是有股票或存款證明就可以了？
-Yes. Not need to sell out your stocks. You also can use your retirement plan such as 401k for I-864 (not need to withdraw any money from 401K, and just provide the proof). If you have a house in US, you also can use the market value minus the loan (if any loan) for I-864. Not need to sell your house.
我記得好象是有一個貧困線，低於該貧線則需要和擔保，那麽這個貧困線是指的在美國資產還是年收入？
-Your income and assets must meet 125% of the US poverty line. See this link:
2024 HHS Poverty Guidelines for Affidavit of Support | USCIS
If you use assets for I-864,, you need to have the assets (cash value) 5 times of the 125% of US poverty line.
For example, you need to have income from your employment $32,275 to meet the requirement of I-864 filing (total three family members in your household). But your current salary income is $30,000, then your asset cash value must at least 5 X $2,275 = $11,375.
（如果是資產，我可以讓我太太把相應存款轉換成美元並匯到我美國銀行的戶頭，但如果是指年收入，那我肯定需要找第3方擔保人了，我想盡量避免麻煩別人）
