donau 早安。对此项税务不熟悉，网搜了一下，应该是和你的信息同源-----

Mail Submission Only: The IRS does not allow e-filing for this specific form on its own, so it must be mailed from abroad.

Use Proper Shipping: It is highly recommended to use services like DHL, FedEx, or UPS, as they provide tracking to ensure the documents are received.

Deadline: If you had no U.S. income, the deadline is generally June 15th. If you are filing with a Form 1040-NR, the deadline is typically April 15th.

Individual Filing: Each person, including dependents, must file their own separate Form 8843.

Address: Send to: Department of the Treasury, Internal Revenue Service Center, Austin, TX 73301-0215, U.S.A. 

我的理解是此表让你在美的存在日期成为“不存在”，可以不被按“美国收入”课税。如果不太费事，建议还是寄一份。IRS 的专业程度在美国算“上等”的，尤其在找人要钱的时候，*_*。

donau 情人节开心。
