Quick Summary: A federal alien-registration requirement may affect some noncitizens who are in the United States for 30 days or more and do not already have proof that they are registered. The rules can be complicated, especially for people without immigration status or with unusual entry histories. Before taking action, it is important to understand whether you are already considered registered and what risks may apply to your situation.

This overview explains the key points in plain language based on the AILA update provided. It is general information, not legal advice.

What Is Alien Registration?

Alien registration is a long-standing federal requirement. In general, foreign nationals age 14 or older who will be in the United States for 30 days or more must be registered and fingerprinted. Adults age 18 or older are also expected to carry proof of registration.

The update states that the federal government began enforcing this requirement on April 11, 2025. It also explains that USCIS created Form G-325R, an online form for certain people who need to obtain proof of alien registration.

Many People May Already Be Registered

Registration is not limited to one immigration category. Many noncitizens already have documents or immigration history that count as proof of registration. Examples listed in the update include lawful permanent residents, people who were admitted with an I-94 or I-94W, people paroled into the United States, people with employment authorization, and people in removal proceedings.

A valid or expired I-94 may still be important proof in some situations. The update also lists documents such as a green card, work permit, certain crewman documents, and certain immigration-court notices as possible evidence of registration.

Because the rules depend on a person’s individual history, do not assume that an expired document means you are not registered. Likewise, do not assume that you must file a new form simply because you are unsure.

Who May Need to Look at Registration More Closely?

The update identifies several groups that may need to review their situation carefully. This includes some Canadians who entered through a land border and did not receive registration evidence, as well as people who entered without inspection and do not otherwise have a registration document.

It may also affect certain people who applied for deferred action or Temporary Protected Status but did not receive proof of registration. Children who turn 14 while in the United States may have a separate registration or re-registration requirement within 30 days of their birthday. Parents or legal guardians are responsible for helping children meet that requirement.

There are also exemptions. The update lists U.S. citizens, people in the United States for fewer than 30 days, certain visa holders who have already been registered and fingerprinted through the visa process, and certain applicants for lawful permanent residence who provided fingerprints.

Registration Can Carry Serious Risks

For a person who entered the United States without inspection, admission, or parole and has not registered, the update says registration may be required. But filing a registration form does not give the person legal immigration status.

The update warns that registering may lead to detention or removal proceedings in some cases. On the other hand, failing to register may also create civil or criminal consequences and could affect a future immigration benefit or visa application. The right choice depends on the person’s facts, including how they entered the country, past applications, current status, and existing documents.

For this reason, the update strongly recommends speaking with a qualified immigration attorney before filing Form G-325R if there is any uncertainty or possible immigration risk.

How the G-325R Process Works

According to the update, Form G-325R is completed online through a USCIS account. The process may include creating an account, submitting the form, attending a biometrics appointment, and waiting for background checks. If the process is completed, proof of alien registration may be made available in the USCIS online account.

The form asks for detailed personal information. This may include the person’s legal name, contact information, current and past addresses, immigration history, biographical information, police or criminal record information, and family information. The form also requires certification under penalty of perjury and permission for USCIS to review records related to eligibility.

Because the form requires detailed answers under oath, it is important to give accurate information and to understand the possible consequences before submitting anything.

Carrying Proof and Updating Your Address

Adults age 18 and older must carry proof of registration. The update states that a willful failure to carry proof may be treated as a misdemeanor, with possible fines, jail time, or both. Using false documents can create separate criminal and immigration consequences.

The update also reminds noncitizens that they generally must notify USCIS of a residential address change within 10 days. Failure to update an address can lead to penalties and may create immigration problems unless the delay is excused or was not willful.

Important Rights Still Apply

The update notes that people living in the United States continue to have basic constitutional rights. This includes the right to remain silent when questioned and the right to speak with a lawyer if arrested. Knowing your rights does not replace legal advice, but it can help you respond carefully in a stressful situation.

FAQ

Do I need to register every time I enter the United States?

Not necessarily. The update explains that many people with immigrant or nonimmigrant visas are already registered. An I-94 or I-94W may serve as proof even after the admission period expires. The effect of a new entry can depend on the type of entry and the document issued.

Does Form G-325R give me legal status?

No. The update clearly states that registration does not grant legal immigration status.

What if I entered the United States without inspection?

The update says some people in this situation may be required to register, but registration can also create serious legal risks. Speak with an immigration attorney before taking action.

What documents can show that I am already registered?

Possible documents listed in the update include an I-94 or I-94W, a green card, an employment authorization document, certain immigration-court documents, and certain other entry or immigration records.

What should I do if this may affect me or my child?

Gather any immigration documents you have and seek legal guidance before filing a registration form or making assumptions about your status.
