Notifying USCIS of a Change of Address Is Important It is the sole responsibility of the applicant/petitioner to ensure USCIS has the correct address information on file.[…]
Non-U.S. Citizens: By law, you must complete Form AR-11 to report any change in permanent address within 10 days.[…]
Note penalty: Willful failure to give written notice to USCIS of a change of address within 10 days is a misdemeanor crime, and could also jeopardize the ability to obtain a future immigration benefit.
A willful failure to give written notice to the USCIS of a change of address within 10 days of moving to the new address is a misdemeanor crime. If convicted, you (or the parent or legal guardian of an alien under 14 years of age who is required to give notice) can be fined up to $200 or imprisoned up to 30 days, or both. The alien may also be subject to removal from the United States. (INA Section 266(b)). Compliance with the requirement to notify the USCIS of any address changes is also a condition of your stay in the United States. Failure to comply could also jeopardize your ability to obtain a future visa or other immigration benefit.
假如你在 USCIS 官网没有帐号，有邮寄的申请在等 USCIS 批准，那么打开网页之后，「Have you filed an immigration-related application or petition and have not yet received a decision notice, card, or document?」 选择 「Yes」，然后输入你的案件信息（case information）、申请人信息（姓名、生日、国籍、身份）、旧地址、新地址，然后留下你的邮箱、电子签名即可。
