妳找個字典查壹下樓上的回答再追問。
妳需要去有移民官辦公的領館申請壹個transportation letter。
北京使館和廣州領館肯定是可以，別的領館不是太清楚，妳可以自己去問壹下。
這個是北京使館的要求：
You must apply for a transportation or boarding letter in person at the Beijing Field Office. These letters are generally issued to a lawful permanent resident (LPR) who has lost or had their Permanent Resident Card (Form I-551) stolen. You must present identification and a report from the local police of the loss of your card.
You must complete an Application to Replace Alien Registration Card (Form I-90) and pay the required fee in U.S. dollars or Chinese RMB. You must also complete required paperwork and submit five color, passport type photos. Verification of your immigration status and the date on which you last departed the United States must be established before a transportation letter will be issued.
必須本人申請，需要面談。
