How do American immigrants invest in real estate tax returns?

According to the current laws in the United States, the property owned by an immigrant applicant in his own name outside the United States is not among the items to be declared. After becoming a green card holder in the United States, the value of his property will be sold for profit in the future. However, after paying the value-added tax on real estate in China, if the tax paid by China is still lower than the capital gains tax 15% in the United States, there may be an obligation to pay American taxes. If investors have real estate, and the real estate is not for rent, there is basically no need to declare it. In addition, there is no need to declare value-added property. Because the American tax law thinks that investors have not become income, when investors sell this part, they have to pay taxes. Investors are advised to evaluate all properties and properties under their names before applying for immigration, so as to prove the source of property when filing tax returns in the future.
