1. 當時回國的原因是奶奶的身體不好，希望他陪在身邊。結果一耽誤就是接近一年。用這個理由會被承認嗎？
-Normally no. But not hurt you to address it.
2. 我一直都在美國，報稅的時候還把他放在dependent，他一直想回來，國內不適應，但是那邊不放。這種情況怎麽陳述比較安全？-Just say: his grandmom in China got sick, and he just wanted to stay with his grandmom for more time because he loves her grandmom so much. He was still a minor at that time, so he of course came back to US to stay with you under your guardiance (family tie) after that period of time.
3. 什麽類型的材料比較好？例如奶奶生病？我報稅的證明？
-Both, if possible.
