父母剛剛去年11月拿到綠卡，請問應該怎麽報稅，他麽國內退休金一個月幾千塊，存款也不多，需要一起報稅嗎，謝謝！
-If your parent is > 65 years old and his personal income is lower than $14,250 of 2021, he does not need to file the tax return. Also, he just became a green card holder for only one month in 2021, so I don't think he needs to file the tax return.
