Hi, thank you so much for your answer! That is a good question! the thing is, we hired an immigration lawyer and his paralegal, and I asked them to use my parents assets, and my husband pay stubs from other country, and they told me we cannot use my parents' assets (properties, investments, money in the bank, their company profits, etc.) or my husband's salary because all of them are in a foreign country, and only assets in the US are accepted. So, in the I864 they only used my house because that is the only asset we have here in the US.
