合法永久居民
有关美国永久居留权的一般信息，请访问DHS-USCIS网站http://www.uscis.gov/greencard
合法永久居民（LPR）可以使用他/她的永久居民卡申请入境美国，如果他/她在美国境外不到一年并且在美国保留住所。
一旦个人以移民签证进入美国，他/她将被授予永久居民身份。永久居民卡（也称为“绿卡”或“I-551”）将邮寄至个人的美国地址。该卡作为有效的身份证明文件，证明该个人有资格在美国生活和工作。使用护照在美国境外旅行的永久居民应在重新进入美国出示永久居民卡。
LPR可以居住在美国，前提是他们不因触犯移民法而被移除（驱逐）。
LPR可以在美国工作。
LPR受美国法律，居住州和当地司法管辖区的保护。
永久居民卡
永久居民卡（通常称为“绿卡”）只能在美国签发或更换。广州办公室无法为您更换绿卡。作为永久居民重新进入美国需要绿卡。如果您将绿卡留在美国，则应安排某人将其发送给您。如果您的绿卡丢失，被盗或被毁，并且在美国以外的地方居住不足364天，需要重新进入美国的许可，您或许可以提交I-131A表格来申请承运人文件。
维持永久居民身份
离开并停留在美国境外连续超过365日的永久居民可能会失去永久居民身份，并可能需要重新进行移民程序，如果他们希望以永久居民身份重新进入美国。在离开美国之前获得再入境许可证的永久居民可以在国外逗留最多2年。
有关获得并保持居住权的信息，请参阅我们的保持绿卡页面。
如果您是美国武装部队成员的配偶或子女或驻扎国外的美国政府文官，您或许可以获得豁免。再入境许可证的更多信息请参阅国务院相关网页。
已过期/将过期绿卡
I-90表格，更换永久居民卡的申请，由合法的永久居民用于申请更换或续签现有的永久居民卡（绿卡）。申请可以电子方式提交。请查看此链接以获取更多信息：“我如何”指南集。
我们的办公室 没有ADIT章。如果您的卡已过期而且您打算前往美国，请查看此链接I-131A。
有条件永久居民

有关其他信息，请查看此链接：有条件永久居民。
再入境许可证
如果您计划在美国境外停留超过一年但不超过两年，则需要再入境许可证才能回美国。提交申请时，您必须在美国境内亲自提交（表I-131）。 DHS-USCIS将把再入境许可证发送到表格上注明的美国地址。您可以选择将再入境许可证寄给总领事馆以便取件。我们将在收到许可证后通知您，您需要亲自前往总领事馆领取文件。 I-131接送指令。
再入境许可证自签发之日起两年之内有效，不得延期或重新生效。
有关如何取得或更换再入境许可证的说明，请参阅表格I-131，旅行证件申请表。
注意：通常，旅行证件的申请人还必须在离开美国之前在申请支持中心（ASC）完成生物识别捕获。如果不这样做，可能会导致申请人失去重新进入该国的许可，并导致拒绝任何其他未决申请。
预先假释
如果您提交I-131表格申请旅行证件，而在获取有效预先假释文件之前就离开美国，您的I-131表格将被视为放弃。
有时个人可能在持有已被批准的预先假释文件的同时有第二个等待获批的预先假释文件。个人可以持有效预先假释文件出国。在这种情况下，待审的I-131表格不会被视为放弃。
如果在您离开美国之前您丢失或未拥有发给您的有效预先假释文件，请联系为你处理申请的美国DHS-USCIS办公室。 DHS-USCIS广州无法为您置换预先假释文件。

Lawful Permanent Residents
For general information about U.S. Permanent Residence, please visit the DHS-USCIS website at http://www.uscis.gov/greencard
A lawful permanent resident (LPR) may apply for admission to the U.S. using his/her Permanent Resident Card, provided he/she has remained outside the United States less than one year and has maintained an un-relinquished domicile in the United States.
Once an individual has entered the U.S. with an immigrant visa, he/she will be granted permanent resident status. A permanent resident card (also called a “Green Card” or “I-551”) will be mailed to the individual’s U.S. address. The card serves as a valid identification document and evidence that the individual is eligible to live and work in the United States.  Permanent residents, traveling outside of the U.S. with their passport, should be prepared to present their permanent resident card to re-enter the United States.
LPRs may live in the United States provided they do not commit any actions that would make them removable (deportable) under the immigration law.
LPRs may be employed in the United States.
LPRs are protected by the laws of the United States, the state of residence and local jurisdictions.
Permanent Resident Cards
A permanent resident card (commonly known as a “Green Card”) can only be issued or replaced in the United States.  Our office cannot provide you with a replacement.  A Green Card is required for re-entry into the U.S. as a permanent resident.  If you left your Green Card in the U.S., you should arrange for someone to send it to you.  If your Green Card has been lost, stolen or destroyed, and you have been outside of the U.S. for less than 364 days without a Permit to Reenter the U.S., you may be eligible to file a Form I-131A to request a carrier document.
Maintaining Permanent Resident Status
Permanent residents who depart and remain outside the U.S. for more than 365 contiguous days risk losing their status and might need to undergo the entire petition and immigrant visa process anew if they wish to re-enter the U.S. as permanent residents. Permanent residents who obtain re-entry permits prior to their departure from the U.S. may remain overseas for up to 2 years.
For information about maintaining your residency receiving your Green Card, see our After a Green Card is Granted page.
If you are the spouse or child of a member of the U.S. armed forces or a civilian employee of the U.S. Government stationed abroad, you may qualify for an exemption.  For more information on obtaining a returning resident visa, see the Department of State’s webpage on returning resident visas.
Expired/Expiring Green Card
The Form I-90, Application to Replace Permanent Resident Card, is used by lawful permanent residents to apply for a replacement or the renewal of an existing Permanent Resident Card (Green Card). The application may be submitted electronically.  Please review this link for additional information: How Do I Guide.
Our office does not issue ADIT stamps.  If your card has expired and you plan to travel to the United States, please review this link I-131A.
Conditional Residents
A conditional permanent resident receives a Green Card valid for two years. The conditional permanent resident must file a petition to remove the condition during the 90 days before the card expires.
For additional information, please review this link: Conditional Residents.
Re-Entry Permit
If you plan to stay outside of the U.S. for more than one year but less than two years in duration, a re-entry permit is needed for readmission. You must be physically present in the U.S. when you file the application (Form I-131). DHS-USCIS will send the re-entry permit to the U.S. address indicated on the form. You may opt to have the re-entry permit sent to the Consulate General for pickup. We will notify you when the permit has been received and you will need to appear at the Consulate General (in person) to collect the document.  I-131 pick-up instruction.
Re-entry Permits are valid for two years from issuance and cannot be extended or revalidated.
Instructions on how to obtain or replace a Re-entry Permit are found under Form I-131, Application for a Travel Document.
Note: Generally, an applicant for a travel document must also complete biometrics capture at an Application Support Center (ASC) prior to departure from the United States. Failure to do so may cause the applicant to lose permission to reenter the country and lead to the denial of any other applications pending.
Advance Parole
If you file Form I-131, Application for Travel Document, to request an advance parole document and depart the United States without possession of an advance parole document that is valid for the entire time you are abroad, your Form I-131 will be considered abandoned.
At times, an individual may have an approved advance parole document while a second one is pending. Individuals may travel on the approved advanced parole document, provided the document is valid for the entire duration of the time abroad. The pending Form I-131 will not be considered abandoned in this situation.
If you have lost or are not in possession of the unexpired Advance Parole Document that was issued to you prior to your departure from the United States, please contact the DHS-USCIS office in the U.S. that issued the document to you. DHS-USCIS Guangzhou cannot issue you a replacement.
If there are urgent humanitarian reasons please refer to humanitarian parole.
Humanitarian Programs
For information about humanitarian programs, please visit www.uscis.gov/humanitarian. 
Asylum
The United States does not grant asylum in its diplomatic premises abroad.  The United States grants asylum only to individuals who are physically present in the United States.
Refugee Processing
Our office does not accept refugee resettlement applications.  If you have questions about eligibility for a referral for refugee resettlement, please contact the United Nations High Commissioner for Refugees (UNHCR) through the UNHCR website.
Humanitarian Parole
For information about humanitarian parole, and filing requirements, visit www.uscis.gov/humanitarian/humanitarian-parole
Humanitarian Parole applications may be submitted to DHS-USCIS in the United States.  We do not accept these applications in Guangzhou.
Naturalization
Many legal permanent residents (LPRs) of the United States have the ultimate goal of becoming American citizens. Once an LPR completes the necessary residence and physical presence requirements (which vary in certain cases), he/she can file an application for naturalization. See the DHS-USCIS website for additional details.
