請問尊敬的8老師，是不是除了填寫Customs Declaration Form，還得填寫FinCEN 105？
-Yes.
這個FinCEN 105也是在飛機上填寫的？
-Yes if your parents want to, or you can fill this form and the US Customs Declaration Form online for your parents, and print them out, then send the completed forms to your parents. Then, your parents can sign them and just provide them to the CBP officer at the port of entry.
Here is the link for FinsCEN 105:

Here is the link for Customs Delcaration Form (Open the fillable form on the up right corner to fill it):

是不是把FinCEN 105跟Customs Declaration Form一起交給空中服務員？
-No. Proivde these forms to the CBP officer at the port of entry.
