来美国那么多年，前两天刚知道有ar 11 form这回事。然后今天想去和移民局报备下换地址，因为最近刚搬家。网上随便查了下被惊到了。后果如此严重。那到底还要不要报备了。之前那么多年搬了10次家了从来没通知过uscis... 懂法律的同学来说说。还有现在去填的话，上一个地址填哪个啊？最早那个还是办绿卡那个？

Penalties for Failure to Comply

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.

You can [url=https://egov.uscis.gov/coa/displayCOAForm.do]submit your change of address online[/url], or call USCIS's customer service number, 800-375-5283, to change your address. You can also complete Form AR-11 (available at [url=http://www.uscis.gov/ar-11]www.uscis.gov/ar-11[/url]) and mail it to the address listed on the form. If you're changing your address through the mail and you have submitted any applications to USCIS that are still being processed, it is a good idea to send a letter to the office that is processing your application to let them know that you have a new address.

But what if you are a lawful permanent resident (LPR) who has never given USCIS a new address, or has already waited, perhaps a year after moving? According to the law, willfully (intentionally) failing to give USCIS your new address is a misdemeanor that can be punished by a fine of up to $200 and up to 30 days in jail.

The law also says that an LPR can actually be removed (deported) for failing to give USCIS a new address, unless the LPR can prove: (1) that the failure to report a change of address was “reasonably excusable” or (2) that the failure was not “willful.”

However, in practice, it is unlikely that the immigration authorities would actually prosecute or deport an LPR who failed to update an address. Immigration authorities have limited resources and cannot go after every LPR who fails to update his or her address. Nevertheless, strict enforcement is always possible in theory.

Therefore, updating your address with immigration is always a good idea. And if you haven't done it when you've moved in the past, do it now and do it every time you move in the future. Or, if you meet all of the eligibility requirements, consider applying for U.S. citizenship. Once you are a U.S. citizen, you'll never have to give USCIS your address again.
