Important: These Rules Are More Nuanced Than They Sound

No single trip length, tax issue, arrest, or paperwork mistake automatically causes every green card holder to lose permanent residence. Immigration consequences depend on the facts. The guidance below explains the practical risks without overstating what the law does.

Rule 1

Carry Evidence of Your Permanent Resident Status

Lawful permanent residents age 18 or older are generally required to carry their Permanent Resident Card, or other qualifying proof of registration, in their personal possession.

What to do

Keep your valid green card with you. Store a secure copy of the front and back separately so you have the card details available if it is lost or stolen. If your card is expired, missing, damaged, or contains incorrect information, take steps to replace it or obtain temporary evidence of status.

Rule 2

Be Careful With Long Trips Outside the United States

A trip lasting more than 180 days does not automatically cancel a green card. However, an absence of more than 180 days can lead to additional scrutiny when you return and may affect continuous-residence requirements for naturalization. Longer or repeated absences may also raise questions about whether the United States remains your permanent home.

A green card is generally used for return after a temporary trip of less than one year. A permanent resident who expects to remain abroad for one year or longer should normally consider applying for a reentry permit before leaving the United States.

What to do

  • Keep trips as short as reasonably possible.
  • Maintain evidence of continuing U.S. ties, such as a home, employment, family relationships, bank accounts, insurance, and tax filings.
  • Apply for a reentry permit before departure when appropriate.
  • Get individualized advice before an extended trip or a pattern of lengthy travel.

A reentry permit is not the same as Advance Parole. Advance Parole is generally used by certain people with pending immigration applications or another qualifying status; permanent residents ordinarily use a reentry permit for planned lengthy travel.

Rule 3

Follow U.S. Tax Filing Rules and Report Worldwide Income

Green card holders are generally treated as U.S. residents for federal tax purposes and must follow the same basic filing rules as U.S. citizens. This normally includes reporting taxable income from both U.S. and foreign sources.

Having no income does not automatically mean that every permanent resident must file a federal tax return. Whether a return is required depends on filing status, age, gross income, self-employment income, and other IRS rules. Even when filing is not required, a tax professional may recommend filing for recordkeeping or other reasons.

What to do

  • Determine whether you meet the IRS filing threshold each year.
  • Report worldwide income and required foreign financial accounts or assets.
  • Do not file as a “nonresident alien” merely because you spent time abroad without first obtaining qualified tax and immigration advice.
  • Address unpaid taxes, unfiled returns, or incorrect filings promptly.

Rule 4

Report a Change of Address Within 10 Days

Most noncitizens, including lawful permanent residents, must report a residential address change to USCIS within 10 days of moving. Updating your address with the U.S. Postal Service does not automatically update it with USCIS.

What to do

  • Use your USCIS online account or Form AR-11 to report the change.
  • Update the address for each pending USCIS case when necessary.
  • Keep confirmation of the submission.
  • Continue monitoring mail and your USCIS account for notices.

Missing a biometrics appointment, interview notice, request for evidence, or other deadline can delay or damage an immigration case. See our overview of common green card problems and how to respond.

Rule 5

Get Legal Advice Before Traveling With a Criminal Record

A DUI, misdemeanor, arrest, dismissed charge, or old conviction does not automatically prevent every permanent resident from returning to the United States. However, some criminal conduct can make a permanent resident inadmissible, deportable, or vulnerable to detention and removal proceedings.

The immigration result may depend on the exact statute, the plea or conviction record, the sentence, the date of the conduct, later offenses, and whether the person is treated as seeking admission when returning from travel.

What to do

  • Do not rely only on the criminal case name, such as “DUI” or “misdemeanor.”
  • Obtain certified court records for every arrest or charge.
  • Consult a qualified immigration attorney before international travel.
  • Do not assume that an expungement, dismissal, or old conviction has no immigration effect.

VisaCoach is not a law firm and does not provide criminal-immigration legal advice. A permanent resident with any arrest or criminal history should obtain advice from an experienced immigration attorney before leaving the United States.
