Can parents lend money to children with American green cards without interest?

According to American tax law and immigration law, parents with American green cards can lend money to their children without interest. However, this kind of loan needs to meet some conditions and restrictions. First of all, the loan needs to be a real and legal transaction, that is, parents do lend money to their children, and clearly stipulate the loan amount, term and repayment method in a written agreement. In addition, the loan needs to be commercially reasonable, that is, the loan amount cannot exceed a reasonable range, and it needs to meet the interest rates and conditions of similar loans in the market. In addition, such loans also need relevant tax returns and records to ensure compliance. In the United States, property transfer, debt relationship and other issues involving taxation and finance are more complicated. Before the specific operation, it is recommended to consult a professional tax consultant or lawyer for detailed guidance and suggestions.
