As a lawful permanent resident, you can build your life and work in the United States while meeting the responsibilities that come with that status. Green card holder responsibilities include keeping your records current, meeting applicable tax and registration requirements, and understanding how time abroad can affect your residence.
Your green card is evidence of permanent resident status. The expiration of a regular 10-year card does not, by itself, end that status. The distinction between a visa, a green card, and immigration status matters when you plan travel or decide which document needs attention.
File the tax returns you are required to file
For federal income tax purposes, resident aliens generally report worldwide income. Whether you must file a return depends on the applicable rules, including your income and filing status. The agency is the Internal Revenue Service, or IRS. State and local obligations may also apply.
The IRS tax guidance for resident and nonresident aliens explains the federal distinction. Do not assume that living abroad or receiving income outside the United States removes your filing obligations. A tax professional can help determine the returns your circumstances require.
A missing return does not automatically mean you have lost permanent residence. There is a more specific immigration concern: claiming nonresident-alien treatment for tax relief, or failing to file because you consider yourself a nonresident alien, can create a rebuttable presumption that you gave up the privileges of permanent residence under the naturalization regulations. Review that issue before relying on such a position.
Work and Social Security records
Lawful permanent residents, including conditional residents, are authorized to work because of their immigration status. A Social Security number is an important employment and tax record; it is not what grants that authorization. The expiration of the physical green card alone does not end an LPR's employment authorization.

If you already have a Social Security number, becoming a permanent resident does not mean you need a new number. Check whether your record or card needs updating. If you requested a number through the immigrant visa process, check that request before submitting another application.
The Social Security Administration's Social Security number guidance for permanent residents explains that option. Follow SSA's current document instructions for your situation rather than assuming every new resident must begin with a separate office application.
Permanent residence also permits petitions for certain relatives, including a spouse and unmarried children. It does not give you all the sponsorship options available to citizens. The guide to relatives a permanent resident can petition for explains those limits before you start a family case.
Keep your green card and registration records current
Check the type of card you received and its expiration date. A regular 10-year card may need renewal or replacement using Form I-90 under the current instructions. Maintaining usable proof matters even though renewing the card is different from renewing permanent resident status.
A two-year conditional card requires a different decision. Removing conditions is not the same as renewing a 10-year card through I-90. For marriage-based conditional residence, the relevant process is Form I-751, with requirements that depend on the filing basis. Do not assume that ordinary card renewal resolves the conditions.
For guidance on a question about your residence documents, you can ask about our green card legal services. Have your card and relevant immigration notices available when discussing your situation.
Two registration duties also belong on your list:
- Carry your registration evidence: if you are 18 or older, carry the registration document issued to you, such as your green card
- Report address changes: notify the immigration authorities of each change of address within 10 days
Keep your document and address records consistent with your current circumstances. If you have a pending case, check the current instructions for updating that case as well; changing a mailing address elsewhere does not establish that the immigration record has been updated.
Check whether Selective Service registration applies
Almost all male U.S. citizens and male immigrants ages 18 through 25 must register with the Selective Service System, subject to the applicable exceptions. That includes many male permanent residents. The age range ends before the 26th birthday; it is not a general requirement for everyone through age 26.
Check the Selective Service System's registration eligibility and exceptions to determine whether the requirement applies to you. Registration records eligibility for a possible draft. It is not enlistment in the military.
Plan travel around your residence
Permanent residence allows international travel, but a green card does not guarantee admission after every trip. Before leaving, consider three separate questions: which documents you will need to return, whether your circumstances show that you continue to reside in the United States, and how the absence may affect a future naturalization application.

These questions can produce different answers for the same trip. Having a return document does not settle abandonment or citizenship eligibility. Review a lengthy absence before departure, especially if your home, work, or family arrangements are shifting abroad.
Return documents and a reentry permit
A valid green card is one document that can satisfy the immigrant-document requirement after a temporary absence of less than one year, subject to the applicable rules. Longer absences can change the documentation required. Do not treat the one-year mark as an automatic loss of status or as a safe allowance for every shorter trip.
A reentry permit is not required for every trip. If you need one, you apply through Form I-131 while physically present in the United States and while holding the required resident status. The permit can address return documentation, but it does not guarantee admission or resolve every question about maintaining residence.
Abandonment and admission are different questions
Abandonment involves the circumstances of your residence and time abroad, not simply the expiration date printed on your card. Repeated or extended stays outside the country can require closer review even when no single trip reaches one year.
An absence of more than 180 days is also one circumstance in which a returning LPR is treated as seeking admission under immigration law. That rule is different from declaring that permanent residence automatically ends after 180 days.
Time abroad can affect naturalization separately
Under the general naturalization rules, an absence of more than six months but less than one year can disrupt continuous residence unless you establish otherwise. An absence of one year or more generally breaks continuity, subject to specific statutory exceptions. Physical presence is a separate requirement.
Form N-470 concerns preserving continuous residence for qualifying employment abroad or another applicable statutory basis. Eligibility and prior-residence requirements matter. It is not a general alternative to a reentry permit, does not preserve LPR status by itself, and does not universally excuse physical-presence requirements.
If citizenship is part of your plans, our naturalization legal services include reviewing residence and travel history. That review can help identify an absence that needs attention before you choose a filing date.
Use the M-618 guide as a starting point
The USCIS guide Welcome to the United States, Form M-618 introduces life in the country and resident rights and responsibilities. It is a useful background resource, not proof that every form instruction, fee, or procedure mentioned in an older copy remains current.
Use current agency instructions for a specific application or reporting task. Keep the broader guide for orientation while checking the requirements that apply to the action you are taking now.
Questions about keeping permanent resident status
Does an expired green card mean I am no longer a permanent resident?
The expiration of a regular 10-year card does not, by itself, end permanent resident status. It does create a documentation issue to address. A two-year conditional card needs separate attention because removing conditions is a different process from ordinary card renewal.
Will I automatically lose my green card if I did not file a tax return?
No automatic conclusion follows from a missing return alone. First determine whether a return was required and why it was not filed. Claiming nonresident-alien treatment can raise a separate immigration issue, so the tax facts and immigration consequences should be reviewed together.
Do I need Form I-131 or N-470 for every trip abroad?
No. A reentry permit requested through I-131 and preservation of continuous residence through N-470 serve different purposes. Neither is a universal travel requirement. The length and purpose of the absence, your return documents, and any naturalization plans determine what needs review.
Before a long absence or when you are unsure which residence document needs attention, call our office to discuss it. Have your green card, relevant immigration notices, and travel history available so we can address the immigration question that concerns you.
