另外,我這次隻給母親申請,沒有申請父親。可是I-797C要求帶“supporting evidence of your relationship, such as copies of any documentation regarding joint assets or liabilities you and your spouse may have together. This may include: tax returns, bank statements, insurance documents, property documents, rental agreements, utility bills, credit cards, contracts, leases, photos, correspondence and/or others."請問這是什麽意思?是不是要帶父母在中國的房產證?
