回複：剛收到不久的“白皮書”丟掉了，

移民局能補發一個嗎？-No.


還是必須重新申請？
-Yes. You also need to provide the evidence that you lost the reentry permit such as police report. You may contact the local USCIS for advices.

謝謝。 人在國內，為此事專門來美打指印，這次又寄丟了，

-You say "剛收到不久的“白皮書”丟掉了" and then you say "為此事專門來美打指印，這次又寄丟了". What do you mean?

很倒黴。謝謝！
