兒媳婦申請我兒子婚姻綠卡，半年前他們提交申請的時候，I-864提供了我兒子的收入，收入足夠了，自己sponsor自己，當時兒媳婦還在上學，最近移民局來信要求提供Co-sponsor,現在兒媳婦已經工作三個月了，需要重新填寫I-864還是怎樣？
-The problem is that your daughter in law had no enough income for the tax return of 2019. So, she had better find a co-sponsor to provide a new I-864 as requested by USCIS.
他們有銀行存款，需不需要提供呀？-If they have enough cash in the savings, they may provide it. The cash must be 5 times of the required amount. For example, if they need $10,000 to meet the I-864 requirement, then their deposit amount in the savings must be $50,000 or more.
非常感謝您！
