謝謝8老師!前幾年經濟不好,又在工作以外拿了個學位,一直沒有離開美國。最近一年才得出空,出去走走,也沒有離開過幾個星期。想想應該是有什麽誤會。
I will go to local CBP Deferred Inspection office and find out why they took it, and there is nothing I am afraid of. BTW, do you know what they do at local CBP Deferred Inspection office, do I need to prepare any documentations, approves, etc.
-Then, I don't think there is a big problem and probably that is just misunderstanding, e.g. your name is the same as someone who may be a suspect of crime, etc. You just need to bring your ID and the copy of the green card or the I-485 approval notice to the CBP local office. That office is responsible for the people who have a problem when entering US. If they don't return your green card for a while, you may file a lawsuit to the immigration court.
